Isibonelo Sobulili Ebudlelwaneni Babantu Nokuzalana

Ukuze abantu bakwazi ukuzizwela izici ezinhle zocansi, kufanele babe nokuqonda okungcono ngemfundo yocansi. Abantu kufanele bazi ngezinhlobo noma izibonelo zocansi kanye nezinzuzo zazo kanye nemiphumela engemihle empilweni nasempilweni enhle yomzimba nengqondo.

Lesi sihloko sichaza izici ezahlukene zocansi, indlela elusiza ngayo ekudaleni isizukulwane esisha, nezinhlobo ezahlukene zemisebenzi yocansi.

Ubulili Buyini?

Ucansi yinoma iyiphi into enzekayo ebandakanya ukuvuselelwa kwezitho zobulili ngokusondelana ngokomzimba. Lungabandakanya izenzo ezahlukene ezifana nokulala ocansini, ucansi lomlomo, noma ngisho nokuziphulula (masturbation). Kubantu, ucansi akusona nje isinyathelo esibalulekile sokuzala, kodwa sinencazelo ebanzi kakhulu kunalokho.

Ivame ukuba indlela yokwakha ubusondele, ukuhlola injabulo yomuntu siqu, nokuxhumana nomlingani. Kuwo wonke umlando, ucansi selube lubhekwa ngezindlela ezihlukene phakathi kwezamasiko. Kwabanye luyinto engcwele, kanti kwabanye luyingxenye yemvelo nejwayelekile yempilo. Kuzo zonke izimo, liyingxenye ebalulekile ku-biology yomuntu futhi lithinta kakhulu izici ezahlukene zempilo yethu.

Ubulili Njengohlobo Lobulili

Igama elithi "ubulili" livame ukusetshenziselwa ukuchaza ukuthi umuntu uyisilisa noma uyisifazane ngokuya ngezimpawu zakhe zomzimba. Lokhu kuhlanganisa izici zomzimba ezifana nezitho zokuzala, amahomoni, namachromosome.

Ubulili Besilisa

Amadoda ngokuvamile abe ne-XY njengama-chromosome abo obulili futhi abe nezitho zokuzala zesilisa, njengezintanga nepenisi [2]. Isidoda yizigameyi zesilisa ezivundisa iqanda lowesifazane ukuze kwenzeke ukukhulelwa. I-testosterone iwuhomoni wobulili besilisa oyinhloko onomthwalo wemfanelo wezinguquko eziningi emadodeni ngesikhathi sobuntanga, njengokujula kwezwi, ukukhula kweenwele ebusweni, nokwanda kwemisipha [3].

Amadoda akhiqiza izigidi zamaseli esidoda nsuku zonke. Umzimba wesilisa udlala indima ebalulekile ekuzaleni ngokunikeza isidoda ukusiza ekudalweni komntwana.

Ubulili Besifazane

Abesifazane ngokuvamile bane-XX njengama-chromosome abo obulili futhi banamazitho okuzala, njengezindlala zamaqanda, isibeletho, ne-vagina [4]. Izindlala zamaqanda owesifazane zikhulula iqanda elilodwa ngomjikelezo ngamunye wokuya esikhathini. Iqanda lilinda isidoda eshubhini le-fallopian ukuze livundiswe kube khona ukukhulelwa.

Amahomoni okuzala abesifazane anjenge-estrogen ne-progesterone alawula izinto ezifana nokuya esikhathini nokukhulelwa [5]. Omunye wemisebenzi ebalulekile yohlelo lokuzala lowesifazane ukondla ingane izinyanga ezi-9 nokuyizala.

Indlela Ucansi Oludala Ngayo Isizukulwane Esisha

Enye yezinjongo eziyinhloko zocansi ukuzala, lapho umbhangqwana ozama ukuba nabantwana ezala kube khona isizukulwane esisha. Nansi indlela okusebenza ngayo:

1. Ngesikhathi socansi, isidoda esivela esithweni sangasese sowesilisa singena emzimbeni wowesifazane.
2. Uma isidoda sihlangana neqanda ohlelweni lokuzala lowesifazane, kwenzeka ukuchumiseka.
3. Iqanda elichumiswe liguqukela esigabeni se-embryo, okuwuphawu lokuyaqala kokukhulelwa. I-embryo idinga izinyanga ezi-9 yokondliwa emzimbeni kamama ngaphambi kokuzalwa.

Ucansi noma ukuzala kubalulekile ekuqhubekeni kwesintu. Ngaphandle kwakho, abantu bebengasoze bakwazi ukudala izizukulwane eziningi.

Ezikhathini zesimanje, kungenzeka ukudala isizukulwane esisha ngaphandle kokubamba iqhaza kunoma yiluphi uhlobo locansi. Lokhu kwenzeka ngenxa yobuchwepheshe bokusiza ukuzala, njenge-in-vitro fertilization (IVF) noma i-intrauterine insemination (IUI) [6]. Lezi zindlela zivame ukusetshenziswa njengokwelashwa kokungabi nenzalo kwabesilisa ngoba zingasiza abantu abanenkinga yokukhulelwa ngendlela yemvelo.

Izinhlobo Ezehlukene Zocansi

Ucansi akupheli ngokufakelana kwezitho zangasese kuphela; luphinde lube nezinye izinhlobo eziningi. Abantu bangakhetha lokho abakuzwayo kubafanele. Nansi izinhlobo zocansi ezivame kakhulu:

1. Ucansi lokufakelana kwezitho zangasese

Ucansi lapho isitho sangasese sowesilisa singena esithweni sangasese sowesifazane yilo ndlela evame kakhulu yokuzala abantu. Ukuze lokhu kwenzeke, ipipi lomuntu wesilisa lingena esithweni sangasese sowesifazane. Usondo olusondelene ngokomzimba lungaholela ku-orgasm bese kuba nokukhishwa kwesidoda. Ngesikhathi sokukhishwa kwesidoda, isidoda singena ohlelweni lokuzala lowesifazane ukuze sifinyelele eqandeni futhi sisichumise, ngaphandle uma kusetshenziswa izindlela zokuvikela ukukhulelwa ukuze kugwemeke ukukhulelwa.

Ngaphandle kokuzala, ukuhlangana ngokocansi kungaqinisa izibopho ngokomzwelo futhi kulethe injabulo ngokomzimba. Kubalulekile ukwenza ucansi oluphephile ukuze ugweme izifo ezithathelwanayo zocansi (STDs) noma ukukhulelwa okungafuneki [7].

2. Ucansi Lomlomo

Ucansi lomlomo luhilela ukusebenzisa umlomo ukuvuselela izitho zangasese zozakwenu. Lolu hlobo locansi alunandima ekuzaleni, lusebenza kuphela njengendlela yokusondeza imibhangqwana nokwandisa ubungani nokusondelana.

Kodwa-ke, kubalulekile ukwazi ukuthi izifo ezithathelwanayo zocansi (STDs) zisengadluliselwa ngocansi lomlomo [8]. Umuntu anganciphisa ingozi yezifo ezithathelwanayo zocansi (STDs) ocansini lomlomo ngokusebenzisa izivikelo, njengama-dental dam noma amakhondomu.

3. Ucansi Lwendunu

Ucansi lwendunu wukuthi ipipi lingene endunu. Lolu hlobo locansi aluvamile futhi luvame ukungaqondwa kahle. Ludinga ukunakekelwa okwengeziwe, njengokusebenzisa ama-lubricant, ukuze kugwenywe ukulimala. Kukhona futhi ingozi ephakeme yokutheleleka ezifo ocansini lwendunu, ngakho kudinga ukuthatha izinyathelo ezifanele zokuzivikela.

4. Ukushaya Indlwabu

Ukushaya indlwabu kuwukuzivuselela izitho zakho zangasese ukuze uthole injabulo yocansi. Kungenye into yemvelo ngokuphelele futhi kunezinzuzo empilweni, njengokunciphisa ingcindezi nengcindezelo yomqondo nokuthuthukisa ukulala. Kwabesilisa, eminye imibiko ikhombisa ukuthi ukushaya indlwabu kungenza kunciphe ingozi yomdlavuza we-prostate [9].

Kunolwazi oluningi olungelona iqiniso nezinganekwane ezizungeze ukushaya indlwabu. Abanye abantu bakholelwa ukuthi ukushaya indlwabu kungaholela ekungabi namandla ombango ngokuhamba kwesikhathi, kodwa akukho bufakazi besayensi obusekela lokhu. Ngokufanayo, abanye bakholelwa ukuthi ukushaya indlwabu kungaholela ekulahlekelweni izinwele, okuyinganekwane nje engenasisekelo sesayensi.

5. Ucansi Olungangenisi

Ucansi olungangenisi lufaka imisebenzi efana nokwanga, ukuthintana, noma ukushayana indlwabu ndawonye. Lungaba inketho enhle kubantu abafuna ukugwema ukukhulelwa noma izifo ezithathelwanayo zocansi (STDs) ngoba aluhileli ukudluliselwa kwama-gamete. Le misebenzi isengaba seduze futhi isize ozakwenu bakhe ukuxhumana okuqinile ngokomzwelo.

Izici Zomphakathi NezePsychology Zezinhlobo Ezihlukene Zocansi

Abantu banezintandokazi ezahlukene uma kuziwa ocansini, futhi lezi zintandokazi zingathonywa isiko, indlela akhuliswe ngayo umuntu, nokuzizwa ekhululekile. Ezinye izinhlobo zocansi, njengocansi lomlomo noma ucansi lwendunu, zingathwalwa ihlazo kwezinye izindawo zomphakathi. Nokho, ukuqonda kangcono nokuhloniphana kunegalelo elihle ebudlelwaneni bocansi obunempilo.

Abantu ababili ababandakanyeka kunoma yiluphi uhlobo lomsebenzi wocansi kumele bavumelane futhi bakwazi ukuxhumana bekhululekile. Ozakwabo kufanele bahlale bekhululekile ukuveza abakuthandayo, abangakuthandi, nemingcele yabo. Ucansi akufanele neze lubandakanye ingcindezelo noma udlame, futhi kumele lube ulwazi ababili abalujabulelayo ngokufanayo.

Indlela Amasiko Nomphakathi Okubumba Ngayo Indlela Esibheka Ngayo Ucansi

Izinkolelo namasiko nemigomo evamile emphakathini kunethonya elikhulu endleleni abantu ababuka ngayo ucansi. Ezinye izizwe noma amasiko zivulekile futhi ziyamukela, kanti ezinye zinemithetho eqinile noma amathabozi.

Uma umuntu ehlala emphakathini lapho abantu bevulekile futhi bemukelelana, lowo muntu uzokhululeka kakhulu ukwabelana ngezinkinga noma ngezinto ahlangabezane nazo eziphathelene nocansi. Ngokufanayo, uma umuntu ekhona ohlotsheni lomphakathi lapho kunamathabozi azungeze ucansi, lowo muntu ngeke akwazi ukuziveza ngokusobala ngezindaba zocansi.

Kubalulekile ukuhlonipha izinqumo zomuntu ngamunye nokwehluka kwamasiko ngenkathi kukhuthazwa ngesikhathi esifanayo ukuxhumana okuvulekile nemfundo ngezempilo yocansi.

Ukubaluleka Kwezempilo Yocansi Nemfundo Ngokocansi

Impilo yocansi iyingxenye ebalulekile yenhlalakahle iyonke. Impilo embi yocansi ayithinti nje kuphela ikhono lokukhulelwa kodwa iphinde iholele engcindezini yengqondo. Kukhona izindlela zok thuthukisa impilo yocansi nesimo sokukwazi ukuzala uma umuntu ebhekene nezinkinga zezempilo yocansi.

Ukwenza ucansi oluphephile, njengokusebenzisa amakondomu noma ukuya njalo ekuhlolweni kwezempilo, kungavimbela izifo ezithathelwana ngocansi nokukhulelwa okungahlelwanga. Imfundo ngokocansi ibaluleke ngokulinganayo. Isisiza abantu baqonde imizimba yabo, bafunde ngobudlelwano obunempilo, futhi benze izinqumo ezinolwazi. Ukuqonda okungaphelele noma ukuntuleka kolwazi kungaholela ezinkingeni ezifana nokuziphatha okungaphephile noma ingcindezi yengqondo.

Uma umuntu ebhekana nezinkinga ezifana nobunzima ekusondelaneni ngesikhathi socansi, kufanele akhulume nomlingani wakhe. Enye indlela wukufuna iseluleko kochwepheshe bezempilo. Izeluleko zochwepheshe zingakusiza uthuthukise indlela owuhlangabezana ngayo nocansi ngenkathi zikuvikela nemiphumela emibi efana nezifo ezithathelwana ngocansi (STDs).

Isiphetho

Ucansi liyingxenye yemvelo nebalulekile yokuphila. Kuyindlela yokuzalanisa nokudala izizukulwane ezintsha. Ngaphezu kokuzalanisa, ucansi luyindlela yokuqinisa ubudlelwano nomlingani. Kunezinhlobo eziningi zocansi, okuhlanganisa ukulala ocansini, ucansi lwangemuva, ucansi lomlomo, nokuzithokozisa ngokwakho. Zonke izinhlobo zocansi zihilela ubusondele bomzimba nokuvuselelwa kwezitho zangasese.

Kubalulekile kokubili kubesilisa nakubabesifazane ukuthi baqonde izingxenye ezihlukene zemfundo yezocansi ukuze bakwazi ukuhlonipha izinqumo zomunye nomunye. Imvume nokuxhumana kungakhuphula kakhulu ulwazi lonke lobudlelwano bomzimba futhi kuqinise isibopho semizwa.

Imibuzo Evame Ukubuzwa

1. Ingabe ukubhucunga (masturbation) kujwayelekile?

Yebo, ukubhucunga (masturbation) kuyisenzo esijwayelekile ngokuphelele. Kungasiza ekunciphiseni ingcindezi, futhi kwenze umuntu azwe injabulo yocansi ngaphandle kwengozi ye-STDs noma ukukhulelwa okungafuneki. Azikho izingozi zempilo ezihambisana nakho uma kwenziwa ngokulinganisela. Kunalokho, kwezinye izimo, ukubhucunga kungaba nezinzuzo empilweni ezifana nokwehlisa ingozi yomdlavuza we-prostate.

2. Ingabe ucansi lungahluka kusuka kwelinye isiko liye kwelinye?

Amasiko ahlukene anemibono ehlukene nezindlela ezahlukahlukene mayelana nocansi. Amanye amasiko avuleleke ekuxoxeni ngocansi, kanti amanye angakwazi ukukubheka njengento yangasese noma enqatshelwe. Imigomo yamasiko ingakwazi ukwakha ngendlela enkulu indlela abantu abacabanga futhi abaziphatha ngayo ngocansi.

3. Umuntu angafunda kanjani ngezempilo yocansi?

Ungafunda ngezempilo yocansi usebenzisa izinsiza ezithembekile ezifana nochwepheshe bezempilo, amawebhusayithi emfundo, noma izincwadi. Izinhlelo zemfundo yezocansi nazo zinikeza ulwazi olubalulekile mayelana nokuzijwayeza okuphephile, imvume, nokugcina ubudlelwano obunempilo.
