Kwayaka: Yekutanga katuni naAlex Martin

Iko kukosha kwekushanduka kwehukuru hwepenisi kwave kuri musoro wekufungidzira kwakawanda, kazhinji kwakaunganidzwa pamwe nenhema yekuti murume phallus iri rakakura kwazvo kupfuura mamwe matemba. Nekudaro, iyo mbichana yemurume iri ipfupi zvishoma, kunyangwe yakafara zvakanyanya, kupfuura mumabhonasi uye zvimupanzi zvakajairika. (Ona yangu Ndira 3, 2015 posvo Kukura Kwemurume uye inotevera Kuwedzera paPenisi Saizi yaFebruary 4.) Zvinoshamisa - kunyangwe paine chikonzero chisingafungidzirwe chekufunga "kunaka kwekukodzera" (nekukumbira ruregerero kune vanoverenga) -hurefu uye upamhi hwemukadzi hazvina kutaurwa.

Kukura kwemukadzi wemunhu

Mukukurukurirana kusingawanzoitika nezvehukuru hwevakadzi, muna 2005 Jillian Lloyd nevamwe vaaishanda navo vakashumudza avhareji yemadzimai kureba kwemasendimita mana chete kuvakadzi makumi mashanu, ane akanyanyisa maviri nehafu nehafu nesendimita. Zvakakosha, kureba kwemukadzi hakuna kusiana pakati pevakadzi vane vana vakaberekwa nevaya vasina. Saka kunyanya kunetsa maitiro ekuberekwa kwevanhu anoita kunge anokonzeresa kugara kure kwemukadzi. Asi David Veale nevamwe vake vakataura mune imwe ongororo ichangoburwa yakafukidza vamwe varume zviuru gumi nezvishanu kuti avhareji yehurefu hwepenisiti yemurume yakamira ingangoita mashanu-ne-kota masendimita. Izvi zvakati pfuurei pane zvakambotaurwa, asi kunyangwe pahukuru hwacho, avhareji yakamira mbichana ndeyechitatu kureba kupfuura wepakati mukadzi. Saka hazvishamise kuti vakadzi vanonzi vane hanya zvakanyanya nezvehurefu hwakawandisa hwepenisi pane kubata kwevanhurume nekodzero dzekuzvitutumadza.

Semazuva ese, kuenzanisa neasina-vanhu mhuka dzinoisa dhata dzevanhu mumaonero. Bhuku raAlan Dixson Kuita Zvepabonde iri zvakare sosi yekutanga, inonyora kureba kwemukadzi kwevanhu uye makumi maviri neshanu eedzimwe mhuka dzinokarirwa. Iwo mana nehafu masendimita anonongedzerwa kuhunhu hwemunhukadzi (kubva kuBancroft, 1989) iri pamusoro pe10% yakakura kupfuura yakataurwa naJillian Lloyd nevamwe vaaishanda navo, asi zvakadaro zvine mutsindo pasi pehurefu hwevhareji yakamira mbichana. Kuronga kurwisa huremu hwevanhukadzi, uchishandisa Dixson dhata, inoratidza kuti kuyerwa kwemadzimai kurema kune huremu hwemuviri neyakareruka kuenzana. Kunyangwe paine kumwe kupararira, maitiro akajeka ari pachena uye avhareji yemadzimai kureba kwevakadzi chaizvo akarara padhuze neakanakisa-akakora mutsara. Saka vakadzi havana kunyanya kusangana nekutsi kwemukadzi kana uchienzaniswa nedzimwe nyani. Zvinoshamisa, zvakadaro, pamasendimita mashoma zvishoma, mukadzi wemadzimba echimpanzi akareba kupfuura vakadzi. Zvakare, pakati nepakati pekuenda kumwedzi, ganda repabonde munzvimbo yekubereka yevakadzi vechimpanzi rakazvimba zvakanyanya, richikurisa hurefu hwesikarudzi neanosvika maviri masendimita.

Nehurombo, dhata rehupamhi hwemadzimai ezvimedu hazviwanzo kushayikwa, saka hazvizivikanwe kuti mukadzi wemukadzi akawedzera pane mamwe matangwe.

Hembe yemunhu

Anatomically, mukadzi chaiye waanomira naye (homologue) yemurume nhengo yake clitoris. Nekudaro, zvinopesana zvakasiyana nekuti mboro ine basa rechipiri rekuita weti uye kuisa mudumbu. Nekupesana, sikarudzi yemukadzi yakabatana chete nekumanikidza uye haina kana kubatanidzwa mukudyara. Iyo clitoris inzvimbo yemukadzi inonyanya kunetseka erogenous zone uye sosi huru yeatomical yekunakidzwa pabonde. Uye yakasarudzika kubva kune iyo weti turakiti, iyo kuvhura kwayo (urethra) inopfuura masendimita kure.

Kunyangwe paine hukama hwayo hwehukama, clitoris yakaregeredzwa zvinonyadzisa nevanoongorora. Mubepa ravo ra2005, Jillian Lloyd nevamwe vaaishanda navo vane mhanza vakataura kuti: "... kunyangwe mamwe mabhuku echangobva kuitika eatomusheni haabatanidzi clitoris pamadhiramu epachiuno echikadzi." Vanyori ava vakapa avhareji yetatu-kotari yemasendimita ekunze kuyerwa kwekirisita kureba. Asi pane musiyano wakakura pamusoro pehusere-zvakapetwa kubva pane chimwe-cheshanu cheye inch kusvika kune imwe nehafu inches. Kunyangwe iri diki diki, iyo inonzi "bhatani rerudo" ine dzinosvika zviuru zvisere zvekunzwa tsinga, yakapetwa kaviri iyo nhamba mudome rejenaguru uye inodarika kuwanda chero kupi zvako mumuviri.

Mapepa maviri achangoburwa akaburitswa muna 1998 na2005 naHelen O'Connell nevamwe vatinoshanda navo vakawedzera kunzwisisa kwedu kwecitoris anatomy. Yekutanga, yakanangana nekuparadzaniswa kwecadavers gumi, yakaratidza kuti clitoris yekunze inoonekwa (iyo glans) inongova chikamu chidiki che "clitoral complex" iyo yakakura kwazvo kupfuura zvaimboonekwa kare. Chokwadi, rakatumirwa blog ra2012 naRobbie Gonzalez rakanyatsofananidza hunyanzvi hwese nechando chisingaonekwe. Bepa repiri rakanyorwa naO'Connell nevamwe vaakashandisa imagineti resonance imaging yekudzidza chimiro chakanakisa cheiyo clitoral system. Padivi rega rega, chikamu chakavanzika cheyakaomeswa chine girobhu uye sechipanji-senge muviri (corpus cavernosum) inotambanudzira ruoko rwunopwanya (crus). Muviri neruoko pamwe zvinoreba kuita mainji mana, kureba zvakanyanya kupfuura glans yekunze. Iyo yakavanzwa clitoral yakaoma ndeye erectile, nepo izvi zvingave zvisiri zvehunyanzvi nezve iyo glans, kunyange ichizadzwa mukati mekusimudzira pabonde. Iwo mababu nemiviri pamwe chete parutivi rwechikadzi kuvhurika uye kubhururuka kana kwakamira, kuchimanikidza.

Mu2010, Odile Buisson akashandisa zviyero zve ultrasound kuongorora basa reiyo clitoris apo vanachiremba vaviri vanozvipira vakaita zvepabonde. Mifananidzo yacho yakaratidza kuti inflation yemukadzi nepenisiti yakatambanudza mudzi wecitoris, zvekuti yaive nehukama hwepedyo nemadziro epamberi echikadzi, anozivikanwa seG-gwapa. Vanyori vakapedzisa kubva mukudzidza kwavo.

Chishoma chisina basa?

Mumashoko aStephen Jay Gould (1993), "Sekuziva kwevanhukadzi kubvira kutanga kwezuva redu, nzvimbo yekutanga yekukurudzira kune nyonganyonga iri pachikirisitu." Uye iro zigadzi rechikadzi rave kungowanzove dingindira rakakura rehurukuro dzekukosha kweiyo clitoris. (Ona yangu June 5, 2014 posvo Vakadzi Orgasms: Kubva kana Kuenderera? ). Tsananguro zhinji dzakatsanangurwa dzinobika kumubvunzo wekutanga wekuti iyo clitoris uye inosanganisirwa maasgasms akagadziridzwa kune rimwe basa kana kungoita vestigial zvigadzirwa. Pamwe chete naGould, Elisabeth Lloyd akasimbisa zvine mutsindo pfungwa yekuti mukadzi akasimudza, senge minyatso yemurume, ingori kutakura kusingabatsiri kubva munzira dzakavandudzwa dzekutanga. Nharo huru inotsigira kududzirwa uku ndeyekuti zvese zviitiko zvevakadzi orgasms uye yekunze clitoris saizi inosiyana zvekuti inoita kunge isina kusefa nesarudzo yakasikwa.

Mune bepa ra2008, Kim Wallen naElisabeth Lloyd vakataura kuti kusiana kwecitoris kureba kwakapetwa nekatatu kukura kupfuura kwemukadzi kana kureba kwepenisi. Zvisinei, mumashoko anotevera, David Hosken naVincent Lynch vakaona zvikanganiso zviviri munharo dzavo. Kutanga, Hosken akasimbisa kuti kusiana kwehukuru hwesikarudzi hakugone kutitaurira chero chinhu pamusoro peyegasm yevakadzi. Chechipiri, saizi misiyano haina, muchokwadi, inosiyana zvakanyanya pakati pekirisita uye nhengo yemurume. Pamwechete, iyo musiyano wekuyera unoshandiswa naWallen naLloyd - iyo coefficient yemusiyano - unodzima misiyano muhukuru hwepakati. Nekudaro, iyo clitoris kureba isingasviki imwechete-yechitanhatu yehurefu hwepenisi, saka kuyerwa kwekuyera kune kwakanyanya kukanganisa. Kuti adzivise dambudziko iri, Lynch akafananidza misiyano mu clitoris uye mavhoriyamu epenis uye haana kuwana musiyano wakakosha. Chero zvazvingaitika, isu hatifanire kutarisira kuwana mibairo ine chinangwa kana tikatarisa kunongedzwa kwechando panzvimbo pechinhu chose!
