Amaphethini okuphendula ngokomzimba nangokwengqondo
Izimpendulo zomzimba

Ukuvuswa kocansi kudala izimpendulo ezahlukahlukene zomzimba, ikakhulukazi ezithweni zobulili (izitho zobulili). Ukuvuswa kowesilisa kowesilisa kuvame ukukhonjiswa ukuvuvukala nokwakhiwa kwenduku lapho igazi ligcwalisa i- corpus cavernosum . Lokhu ngokuvamile kuyisibonakaliso esivelele futhi esinokwethenjelwa sokuvusa ucansi kwabesilisa. Ngo owesifazane, ngokobulili imikhondo ukuqhanyelwa lenyuka igazi ligeleze clitoris futhi ngemomozi, kanye transudation sowesifazane sangasese - the seeping umswakama ngokusebenzisa izindonga lwesitho sangasese sowesifazane esebenza njengesikhali Lubrication .
Owesifazane

Ukuqala kokuvuswa kocansi emzimbeni wowesifazane kuvame ukuphawulwa ngokuthambisa kwesitho sangasese sowesifazane (ubumanzi; yize lokhu kungenzeka ngaphandle kokuvuka ngenxa yokutheleleka noma ukukhiqizwa kwamafinyila womlomo wesibeletho okuzungeze i-ovulation), ukuvuvukala nokuqina kwezitho zangasese zangaphandle, nokwandiswa kwangaphakathi nokwandiswa kwe isitho sangasese sowesifazane.Kube nezifundo zokuthola izinga lokuhlangana phakathi kwalezi zimpendulo zomzimba nokuzizwa kowesifazane ngokuzithoba kokuvuswa ngocansi: okutholakele imvamisa ukuthi kwezinye izimo kunokuhlangana okuphezulu, kanti kwezinye, kuphansi ngokumangazayo.

Ukuvuselelwa okuqhubekayo kungaholela ekuqhubekeni kobumanzi besitho sowesifazane kanye nokufakwa okuthe xaxa nokuvuvukala kwe- clitoris ne- labia, kanye nokubomvu okukhulayo noma ukumnyama kwesikhumba kulezi zindawo njengoba ukugeleza kwegazi kukhuphuka. Izinguquko Ngaphezu izibilini kwenzeke kufaka phakathi ukuma yangaphakathi sangasese futhi isikhundla kwesibeletho ngaphakathi ukhalo . Olunye ushintsho lubandakanya ukwanda kokushaya kwenhliziyo kanye nomfutho wegazi, ukuzwa kushisa futhi kufutha futhi mhlawumbe uhlangabezana nokuthuthumela. Ukuqhuma kocansi kungadlulela esifubeni nasemzimbeni ophezulu.

Uma ukugqugquzela ngokocansi kuqhubeka, ukuvusa ucansi kungahle kufinyelele ku- orgasm . Ngemuva kwe-orgasm, abanye besifazane abafuni okunye ukukhuthazwa futhi ukuvuswa kocansi kuyashesha. Iziphakamiso zishicilelwe ngokuqhubeka nenjabulo yezocansi nokusuka kwi-orgasm eyodwa kuya ekuvuseleleni okuqhubekayo nokugcina noma ukubuyisa isimo sokuvuka ngocansi okungaholela ekuvuseleleni kwesibili nokwalandela. Abanye besifazane bake babhekana nama-orgasms amaningi kangaka ngokuzenzekelayo.

Ngenkathi abesifazane abasebasha bengaqala ukuvuswa ngocansi kalula, futhi bafinyelele i-orgasm ngokushesha okukhulu ngokugqugquzela okulungile ezimeni ezilungile, kukhona izinguquko zomzimba nezingokwengqondo ekuvusweni kwabesifazane kanye nezimpendulo njengoba bekhula. Abesifazane abadala ukukhiqiza Lubrication kancane lwesitho sangasese sowesifazane kanye izifundo uphenyo izinguquko lamadigri ukwaneliseka, imvamisa ocansini, ukufisa, imicabango yobulili kanye fantasies, inkanuko yobulili, izinkolelo mayelana nezimo zengqondo wobulili, ziholele ubuhlungu, kanye nekhono ukufinyelela eqophelweni lokwaneliseka ngokobulili kwabesifazane ama-40s abo nangemva kokunqamuka kokuya esikhathini . Ezinye izinto ziye zafundwa kufaka phakathi okuguquguqukayo kwezenhlalo-yabantu, ezempilo, okuguquguqukayo kwengqondo, okuguquguqukayo kozakwethu njengempilo kazakwenu noma izinkinga zocansi, nokuhlukahluka kwendlela yokuphila. Kubukeka sengathi lezi ezinye izinto zivame ukuba nomthelela omkhulu ekusebenzeni kwabesifazane kwezocansi kunasesimweni sabo sokuya esikhathini. Ngakho-ke kuthathwa njengokubalulekile ngaso sonke isikhathi ukuqonda "umongo wezimpilo zabesifazane" lapho ufunda ubulili babo.

Amazinga e- estrogen ancishisiwe angahlotshaniswa nokoma kwesitho sowesifazane sangasese nokwakhiwa okuncane kwe-clitoral lapho kuvuswa, kepha akuhlobene ngqo nezinye izici zentshisekelo yezocansi noma zokuvuka. Kwabesifazane asebekhulile, ukwehla kwethambo le-pelvic muscle kungasho ukuthi kuthatha isikhathi eside ukuvusa imizwa kuholele ku-orgasm, kunganciphisa ukuqina kwama-orgasms, bese kudala isisombululo esisheshayo. Isibeletho ngokujwayelekile sisebenza ngesikhathi se-orgasm futhi, ngokuguga, lezo zingqinamba zingaba buhlungu empeleni.
Owesilisa

Kujwayelekile ukuhlanganisa ukwakhiwa kwenduku nokuvuswa kobulili kowesilisa. Ukugqugquzela ngokomzimba noma ngokwengqondo, noma kokubili, kuholela ekuvuseleleni i- vasodilation futhi ukwanda kokugeleza kwegazi kufaka izindawo ezintathu zesiponji ezihamba ngobude bepipi (i- corpora cavernosa ne- corpus spongiosum ). Umthondo ukhula ukhule futhi uqine, isikhumba sesikhosho sidonswa siqine, futhi amasende adonswa abhekiswe emzimbeni. Kodwa-ke, ubudlelwano phakathi kokumiswa nokuvuka akuyona eyedwa. Ngemuva kweminyaka yabo ephakathi kwamashumi amane, amanye amadoda abika ukuthi awahlali njalo uma evuswa ngocansi. Ngokulinganayo, ukwakhiwa kwesilisa kungenzeka ngesikhathi sokulala (i- penile tumescence yasebusuku ) ngaphandle kokuvuswa kocansi noma ngenxa yokugqugquzela ngomshini (isb ukuzihlikihla ngombhede) kuphela. Insizwa - noma eyodwa ene-libido eqinile - angathola ukuvuswa okwanele ngokocansi ukuze kuvuswe umphumela womcabango odlulayo, noma nje ukubona komuntu odlulayo. Uma sesimile, ipipi lakhe lingathola ukukhuthazeka okwanele ngokuxhumana nengaphakathi lezingubo zakhe ukuze lilondolozwe futhi likhuthazwe isikhathi esithile.

Ngenkathi ukuvusa inkanuko yobulili nokukhuthaza kuqhubeka, kungenzeka ukuthi ubukhazikhazi noma ikhanda lomthondo oqondile lizokhula kakhulu futhi, njengoba izitho zangasese ziqhubeka nokufakwa igazi, umbala wazo uyajula namasende angakhula afike ku-50% omkhulu. Njengoba amasende aqhubeka nokukhuphuka, umuzwa wemfudumalo ungakhula ubazungeze kanye ne-perineum. Ngokuqhubeka nokuvuselelwa ngokocansi, izinga labo lenhliziyo liyakhuphuka, umfutho wegazi uyakhuphuka futhi ukuphefumula kuyashesha.Ukwanda kokugeleza kwegazi ezithweni zobulili nakwezinye izifunda kungaholela ekuqothulweni kocansi kwamanye amadoda.

Njengoba ukugqugquzela ngokocansi kuqhubeka, i- orgasm iqala, lapho imisipha yangaphansi kwe- pelvic, i- vas deferens (phakathi kwamasende kanye ne-prostate), ama -vesicles wesilisa kanye ne-prostate gland ngokwayo ingaqala ukuhlangana ngendlela ephoqa isidoda nesidoda urethra ngaphakathi kwepipi. Uma lokhu sekuqalile, kungenzeka ukuthi indoda izoqhubeka nokukhipha i-ejaculate ne-orgasm ngokugcwele, noma ngaphandle kokuvuselela okunye.

Ngokulinganayo, uma ukukhuthazwa kocansi kuyeka ngaphambi kwe-orgasm, imiphumela ebonakalayo yokukhuthaza, kufaka phakathi i- vasocongestion, izoncipha ngesikhathi esifushane. Ukugqugquzela okuphindiwe noma okude ngaphandle kwe-orgasm kanye ne-ejaculation kungaholela ekuphatheni kabi emasendeni (okuhambisana negama lesilayidi elithi " amabhola aluhlaza " ).

Ngemuva kwe-orgasm kanye ne-ejaculation, amadoda ajwayele ukuhlangabezana nesikhathi sokuphika esivezwa ukulahleka kokwakhiwa kwawo, ukuncipha kunoma yikuphi ukuqhuma kocansi, ukungabi nentshisekelo kwezocansi, kanye nomuzwa wokuphumula ongabangelwa yi-neurohormones oxytocin neprolactin . Amandla nobude besikhathi sokuphikisa bungaba bufushane kakhulu ensizweni evuswe kakhulu esimweni esivusa kakhulu, mhlawumbe ngaphandle kokulahleka okuphawulekayo kokwakhiwa.Kungaba isikhathi eside njengamahora ambalwa noma izinsuku emadodeni aphakathi nendawo nangaphezulu.
Ezinye izilwane

Ngenkathi ubulili bomuntu buqondakala kahle, ososayensi abaqondi ngokuphelele ukuthi ezinye izilwane zihlobana kanjani nezocansi.Kodwa-ke, ucwaningo lwamanje lubonisa ukuthi izilwane eziningi, njengabantu, zijabulela ubudlelwane bobulili obungagcini ekukhiqizeni.Ama-dolphins nama- bonobos, isibonelo, zombili ziyaziwa ngokusebenzisa ubulili "njengethuluzi lomphakathi lokuqinisa nokugcina izibopho."Sekuyisikhathi eside izazi ze-Ethologists zibhala ukuhwebelana ngocansi ukukhuthaza ukuhlangana kweqembu ezilwaneni zenhlalo . Ukuqinisa ubugqila bezenhlalo kungenye yezinzuzo ezikhethwe kakhulu ezikhethiwe zethiyori yokukhetha iqembu . Ochwepheshe ekuziphendukeleni kocansi njengoJohn Maynard Smith baxhasa umbono wokuthi ukushintshaniswa kwezinhloso zocansi kusiza ukujiya futhi kutholakale ukuhlangana kwama- alleles kubantu abahlala bodwa ngakho-ke kungaba namandla amakhulu ekuziphendukeleni kwemvelo . UMaynard Smith ubhale kaningi kakhulu mayelana nokusetshenziswa kwe-seminal fluid swapping theory ye-assortment of alleles njengokukhonjiswa okunembe kakhudlwana komgomo we-Hardy-Weinberg ezimweni lapho abantu bezalana kakhulu.
