Ngaba ubungakanani bokubaluleka kwabafazi?

Ukubaluleka kokuvela kobukhulu bepenisi bekusisihloko sokuqagela okuninzi, kuhlala kupakishwe ngentsomi yokuba iphallus yomntu inkulu kakhulu kunezinye izilwanyana. Nangona kunjalo, ipeni lomntu eneneni imfutshane kancinci, nangona ibanzi kakhulu, kuneebhonobos kunye neetshimpanzi eziqhelekileyo. (Jonga iposti yam kaJanuwari 3, 2015 Ubungakanani Bepenisi kunye nokulandelelana Ukwandisa ubungakanani bePenis kaFebruwari 4.) Ngokumangalisayo — ngaphandle kwesidingo esingathandabuzekiyo sokuthathela ingqalelo “ukulunga kokulunga” (ngokucela uxolo kubalo-manani) -ubude nobubanzi belungu lobufazi akukakhankanywa.

Ubungakanani belungu lobufazi lomntu

Kwingxoxo enqabileyo yemilinganiselo yabasetyhini, ngo-2005 uJillian Lloyd kunye noogxa bakhe baxela umyinge wobufazi obungaphantsi kweesentimitha ezine kwabasetyhini abangama-50, ngokugqitha kweesentimitha ezimbini ezinesiqingatha kunye nee-intshi ezintlanu. Ngokubalulekileyo, ubude besini abuzange buhluke phakathi kwabasetyhini abanokuzalwa kwangaphambili kunye nabo bangenabo. Ke le nkqubo inzima kakhulu yokuzalwa komntu ibonakala ngathi ayibangeli kuqhubeka kuhlala ixesha elide kwilungu lobufazi. Ukanti uDavid Veale kunye noogxa bakhe baxele kuvavanyo lwamva nje olugubungela amanye amadoda angama-15,000 ukuba ubude obuphakathi bendoda eyomileyo bumalunga nee-intshi ezintlanu nekota. Oku kuncinci kunokuba bekuxeliwe ngaphambili, kodwa nakobobukhulu, ubudoda obumiselweyo obuphakathi buyinto yesithathu ubude kunexesha lobufazi. Ke ayothusi into yokuba abasetyhini baxhalabile ngaphezulu kobude obugqithisileyo bendoda kunokuzixakekisa ngamalungelo okuqhayisa.

Thelekisa noonina abangengobantu

Njengesiqhelo, uthelekiso lwee-primates ezingezizo ezabantu zibeka idatha yoluntu ngokwembono. Incwadi ka-Alan Dixson Ukwabelana ngesondo kwangaphambili Iphinda ibe ngowona mthombo uphambili, udwelise ubude besini babantu kunye nezinye 27 iintlobo zezilwanyana ezinqabileyo. I-intshi ezine ezinesiqingatha ezichaziweyo kubude belungu lobufazi lomntu (ukusuka eBancroft, ngo-1989) imalunga ne-10% enkulu kunokuba kuchaziwe nguJillian Lloyd kunye noogxa bakhe, kodwa nangoku ingaphantsi kobude bepenisi ethe nkqo. Ukucwangcisa ngokuchasene nobunzima bomzimba wabasetyhini, kusetyenziswa idatha kaDixson, kutyhila ukuba isikali sobude besini kumzimba ubunzima ngokulingana okulula. Ngaphandle kokuchithachithwa, imeko ecacileyo iyabonakala kwaye umndilili wobude besini abasetyhini ulala kufutshane nomgca ofanelekileyo. Ke abantu basetyhini abanabufazi obude ngokukodwa xa kuthelekiswa namanye amantshontsho. Ngokumangalisayo, nangona kunjalo, ngaphezulu kweesentimitha ezintlanu, ubufazi beetshimpanzi zowasetyhini ngokucacileyo bude kakhulu kunabafazi. Ngaphaya koko, phakathi embindini wokuya exesheni, ulusu lwesini kummandla wesini weechimpanzee zabasetyhini ludumbile, lwandisa ubude besini phantse ziisentimitha ezimbini.

Ngelishwa, idatha kububanzi lobufazi bama-primates iyasilela ngokubanzi, ke ayaziwa nokuba ubufazi bebhinqa bubanzi ngokuthe gabalala kunezinye izilwanyana.

Ikhoza lomntu

Ngokwemvelo, iqabane elichanekileyo lomfazi (i-homologue) lobudoda bendoda yi-clitoris yakhe. Nangona kunjalo, yahluke ngokucacileyo kuba ilungu lobudoda linendima edibeneyo yokuchama kunye nokusasaza. Ngokwahlukileyo, i-clitoris yomfazi inxulunyaniswe kuphela nokukhuphela kwaye ayibandakanyekanga nakwichumiso. I-clitoris yeyona ndawo inomdla kakhulu kumfazi kwaye ingoyena ndoqo wolonwabo ngokwesondo. Kwaye ibekwe yodwa kumchamo wokuchama, ovulekileyo (urethra) ungaphezulu kwe-intshi kude.

Ngaphandle kokunxibelelana ngokukodwa nokukhuphela, i-clitoris iye yatyeshelwa ngehlazo ngabaphandi. Kwiphepha labo lowama-2005, uJillian Lloyd noogxa bakhe bagqabaza bathi: “... kwanezinye iincwadi zakutshanje zeatomy azibandakanyi iklayi kwimizobo yamathambo ebhinqa.” Aba babhali banike umndilili weekota ezintathu ze-intshi ubude be-clitoris engaphandle. Kodwa kukho umahluko omkhulu kububanzi obuphindwe kathathu ukusuka kwisihlanu se-intshi ukuya kwi-intshi enye enesiqingatha. Ngaphandle kobuncinci bayo, into ebizwa ngokuba "liqhosha lothando" iqulethe imicu yemithambo-luvo eyi-8,000, iphindaphindwe kabini kwinani lendoda kunye nokugqitha kobuninzi bayo naphi na emzimbeni.

Amaphepha amabini akutshanje apapashwe ngo-1998 nango-2005 nguHelen O'Connell noogxa bakhe bakuphucula kakhulu ukuqonda kwethu nge-clitoris anatomy. Eyokuqala, esekwe ekusasazeni ii-cadavers ezili-10, ityhile ukuba iklitri ebonakalayo yangaphandle (i-glans) yinxalenye nje enye encinci ye "clitoral complex" ebanzi kakhulu kunangaphambili. Ewe, iposti yebhlog ka-2012 ebhalwe nguRobbie Gonzalez ufanise ngokufanelekileyo ubunzima ngokubanzi kwindawo engabonakaliyo yomkhenkce. Iphepha lesibini lika-O'Connell kunye noogxa basebenzise imaging resonance imaging ukufunda ubume benkqubo yeclitoral. Kwicala ngalinye, icandelo elifihliweyo lobunzima liqukethe ibhalbhu kunye nomzimba ofana nesiponji (corpus cavernosum) olulela kwingalo ye-tapering (crus). Umzimba kunye nengalo zidibene zimalunga nee-intshi ezine ubude, zinde kakhulu kune-glans yangaphandle. Ubunzima obufihliweyo be-erectile, ngelixa le nto isenokungabi yinyani kwezobuchwephesha, nangona iye yafakwa ngexesha lokuvuselelwa ngokwesondo. Iibhalbhu kunye nemizimba zidibene kuvula lobufazi kunye ne-bulge xa ​​zime, ziyicinezele.

Ngo-2010, u-Odile Buisson wasebenzisa i-ultrasound scans ukuphanda indima ye-clitoris ngelixa oogqirha ababini bokuzithandela babandakanyeka ekwabelaneni ngesondo. Imifanekiso ityhile ukuba ukunyuka kwamaxabiso kwilungu lobudoda kusolula ingcambu ye-clitoris, kangangokuba ibinobudlelwane obusondelelene kakhulu nodonga lwangaphambili lobufazi, obizwa ngokuba yi-G-spot. Ababhali baqukumbele kuphando lwabo: "I-clitoris kunye nelungu lobufazi kufuneka libonwe njengeyunithi yokwenziwa komzimba kunye nokusebenza okusebenzayo ngokungena kwilungu lobufazi ngexesha lokwabelana ngesondo."

Ngaba yintsalela engasebenziyo?

Ngamazwi kaStephen Jay Gould (1993), “Njengokuba abantu basetyhini besazi kwasekuqaleni kweli xesha lethu, eyona ndawo iphambili yokukhuthaza amaziko e-orgasm kwi-clitoris.” Kwaye i-orgasm yabasetyhini ngokubanzi ibingumxholo ophambili kwiingxoxo ngokubaluleka kweklitoris. (Jonga eyam kaJuni 5, 2014 iposti I-Orgasms yabasetyhini: Ukuhla okanye ukuKhanya? ). Iinkcazo ezininzi ezicetywayo zibilise kumbuzo osisiseko wokuba ingaba iklitoriy kunye nee-orgasms ezinxulumene noko zilungelelaniselwe umsebenzi othile okanye ziveliso nje. Kunye noGould, u-Elisabeth Lloyd wanyanzela ngamandla umbono wokuba i-clitoris yabasetyhini, njengeengono zendoda, yinto nje engenamsebenzi yokuhamba kwindlela ekwabelwana ngayo yokuqala. Ingxoxo ephambili exhasa olu toliko kukuba kokubini ukwenzeka kwe-orgasms yabasetyhini kunye nobungakanani be-clitoris yangaphandle ziyahluka kangangokuba zibonakala ngathi azicocwanga ngokhetho lwendalo.

Kwiphepha lowama-2008, uKim Wallen no-Elisabeth Lloyd baxela ukuba umahluko kubude be-clitoris ungaphezulu kokuphindwe kathathu bukhulu kunelobufazi okanye lobudoda. Nangona kunjalo, kumagqabantshintshi alandelayo, uDavid Hosken kunye noVincent Lynch baqaphela iimpazamo ezimbini kwingxoxo yabo. Okokuqala, uHosken wagxininisa ukuba umahluko kubungakanani be-clitoris awunakusixelela nto malunga ne-orgasm yabasetyhini. Okwesibini, umahluko wobukhulu awenzi, enyanisweni, wahluke kakhulu phakathi kweklitorikhi kunye nepipi. Ngokomgaqo, umahluko osetyenzisiweyo nguWallen noLloyd-ukungalingani kokungafani-ucima umahluko kubungakanani obuqhelekileyo. Nangona kunjalo, ubude be-clitoris bungaphantsi kwesinye kwisithandathu sobude bepenisi, ke impazamo yokulinganisa inefuthe elikhulu. Ukuthintela le ngxaki, uLynch uthelekise umahluko kwi-clitoris kunye neepenisi kwaye akafumananga mahluko ubalulekileyo. Ngayiphi na imeko, asinakulindela ukufumana iziphumo ezinentsingiselo ukuba sijonga incam yomkhenkce endaweni yayo yonke loo nto!
