Iimpuku zabasetyhini abanxibe iibhatyi azifani nabasetyhini abanxibe iimpahla zangaphantsi. Kuzo zonke iintlobo zezilwanyana, ukuziphatha ngokwesondo ilawulwa yintsebenziswano entsonkothileyo phakathi kwezenzo zamahomoni kubuchopho bethu. Kuphononongo olutsha lwe-quirky, abaphandi bahombise iimpuku zabasetyhini ngeebhatyi ezikhethekileyo ukuze baqonde ngcono ukuba yintoni eguqula iimpuku zamadoda. Ezi ziphumo, iboniswe kwi Intlanganiso yonyaka yoMbutho weNeuroscience kwinyanga ephelileyo, inokunceda ukuphendula umbuzo ovuthayo: Kutheni amadoda ethanda iingubo zangaphantsi?
A Iqela leYunivesithi yaseConcordia elikhokelwa nguJames Pfaus kwaye uGonzalo Quintana Zunino uye wabonisa ngaphambili ukuba iimpuku zamadoda zinokulungiswa ukuba zikhethe ukukhupha malunga neentombi ezithwala ivumba elithile (i-almond, ukuba uyazibuza). La madoda avuzwa ngexesha lawo emva kokuphuma kwe-ejaculatory. Iqela liphinde lafumanisa ukuba iigundane ezinyulu eziziintombi ezinxibe ijacket ekhethekileyo ye-rodent-tethering ngexesha lawo lokuqala lokwabelana ngesondo zilahlekelwa yinkanuko yesini kunye nenkuthazo ukuba ibhatyi isusiwe ngaphambi kwesinye isenzo sokubambisana.
Ngokudibeneyo, ezo zifundo zibonisa ukuba ivumba liba yinto ehambelana neqabane kunye nendlela ibhatyi esebenza ngayo njengomxholo wokuvusa inkanuko yesini. Ngoku, iqela elifanayo belifuna ukwazi ukuba ijacket yempuku inokuthi isebenze njengesixhobo sokuseka "i-conditioned ejaculatory preference" (CEP). Oko kukuthi, ibhatyi iyavula?
Kolunye ulingo, iimpuku zamadoda ezili-12 eziye zafumana iimvavanyo ezili-14 zokukhupha iijaculation ezininzi kunye nabasetyhini abanxibe ibhatyi yeempuku. Ngexesha lovavanyo lokugqibela, amadoda abekwe kwibala elivulekileyo kunye nabasetyhini ababini abalwamkelayo ngokwesondo: Omnye wanxiba ibhatyi, omnye enxibe isuti yakhe yokuzalwa. Amadoda amaninzi aqala ukukhupha iimazi kunye nabasetyhini abanxibe ibhatyi. Kwakhona babeza kuyiva ibhatyi ngamabhovu abo ngelixa bekhwelana.
Kuvavanyo lwesibini, amadoda alishumi elinesibini aye avezwa ngokulandelelana kwabasetyhini abanxibe ibhatyi esabelayo ngokwesondo kwaye emva koko kwaba ngabafazi abangaphangeliyo, abangasamkeliyo ngokwesondo. Kuvavanyo lokugqibela oluvulekileyo, amadoda akhupha ngakumbi, kwaye ngokukhawuleza, kunye nabasetyhini abafake ibhatyi. Iqela emva koko lahlola iingqondo zala madoda, lizithelekisa neengqondo zamadoda angazange aqeqeshelwe ukudibanisa ibhatyi nesondo. Amadoda akhwelana namabhinqa anxibe ibhatyi, I-Live Science iyacacisa, wabonisa umsebenzi ongakumbi kwiziko lolonwabo lobuchopho.
Amadoda, afumanisa ukuba, angafunda ukudibanisa iimpawu ze-somatosensory - ukuvakalelwa kunye nokubona kwempahla ethile, kule meko - ngokuvuselela ngokwesondo. Ngamanye amazwi, njengoko UQuintana Zunino uxelela iLive Science, amadoda afunda ukuba “sihlandlo ngasinye iqabane lam linxibe impahla yangaphantsi, ndiya kuba neentlobano zesini.”
