Ariko se, iyo umuntu avuye mu migani, ibihuha n’ibivugwa ku mbuga za internet, akareba ibyo ubushakashatsi bwa siyansi bumaze imyaka myinshi bugaragaza, ubunini bw’igitsina bugira uruhare rungana iki mu kunyurwa mu mibonano mpuzabitsina?

Ikibazo cyabaye isoko y’impungenge ku bagabo benshi

Mu mwaka wa 2015, ubushakashatsi bwimbitse bwatangajwe mu kinyamakuru cya siyansi British Journal of Urology International (BJUI) bwasesenguye imibare y’abagabo barenga 15,000 bo mu bihugu bitandukanye.

Ubwo bushakashatsi bwari buyobowe na David Veale bwagaragaje ko abagabo benshi bafite impungenge ku bunini bw’igitsina cyabo kurusha uko byakagombye.

Abashakashatsi basanze abagabo benshi batekereza ko bafite igitsina gito nyamara kiri mu bipimo bisanzwe rwose. Ibi byatumye bemeza ko ikibazo gikomeye atari ubunini ubwabwo, ahubwo ari uburyo abantu babutekerezaho.

Veale n’itsinda rye banditse ko hari icyuho kinini hagati y’uko abagabo bibona n’uko imibare nyayo ya siyansi ibigaragaza.

Uko ibipimo bya siyansi bibivuga

Ubushakashatsi bwa BJUI bwagaragaje ko impuzandengo y’uburebure bw’igitsina cy’umugabo igihe cyahagaze neza (erect penis) ari hafi ya santimetero 13.12.

Ibi ni ngombwa kubisobanukirwa kuko abantu benshi bubaka imyumvire yabo ku byo babonye muri filime z’urukozasoni cyangwa ku nkuru zidakurikiza ukuri kwa siyansi.

Mu by’ukuri, abaganga bavuga ko abagabo benshi bari hagati y’ibipimo bisanzwe kurusha uko babyibwira.

Abahanga mu by’imitekerereze bavuga ko igitsina cy’umugabo cyahawe agaciro karenze ako gifite mu mico myinshi.

Mu gitabo The New Male Sexuality, impuguke mu mitekerereze Bernie Zilberge yasobanuye ko kuva kera abantu bagiye bahuza ubunini bw’igitsina n’imbaraga, ubutwari cyangwa ubugabo, nubwo nta bushakashatsi bubyemeza.

Yagaragaje ko iyo myumvire yakomeje kwiyongera kubera itangazamakuru, filime n’ubucuruzi bushingiye ku gutera ubwoba abagabo kugira ngo bagure ibicuruzwa bivuga ko byongera ubunini bw’igitsina.

Icyo abagore benshi bavuga mu bushakashatsi

Mu gihe abagabo benshi bahangayikishwa n’ubunini bw’igitsina, ubushakashatsi bwinshi bwibanze no ku kureba icyo abagore ubwabo babivugaho.

Ubushakashatsi bwatangajwe muri The Journal of Sexual Medicine bwerekanye ko abagore benshi bashyira imbere ibintu nk’itumanaho ryiza, urukundo, ubwizerane, isuku, kumva batekanye no kwitabwaho kurusha uko baha agaciro ubunini bw’igitsina.

Ibi ntibisobanuye ko ubunini budafite uruhare na ruto, ariko bigaragaza ko atari cyo kintu cy’ingenzi nk’uko abantu benshi babitekereza.

Mu yandi magambo, ubushakashatsi bwinshi bwerekana ko kunyurwa mu mibonano mpuzabitsina ari igisubizo cy’ibintu byinshi bikorana, aho kuba igisubizo cy’ubunini bw’urugingo rumwe gusa.

Siyansi ivuga iki ku mubiri w’umugore?

Kugira ngo umuntu yumve neza iki kibazo, ni ngombwa gusobanukirwa n’imiterere y’umubiri w’umugore.

Mu bushakashatsi bwakozwe n’inzobere mu buvuzi bw’imyororokere Helen O’Connell, hagaragajwe ko ibice byinshi by’ingenzi bifasha umugore kugira ibyishimo byo mu mibonano mpuzabitsina biherereye mu gice cyo hanze cyangwa hafi y’umwinjiriro w’igitsina.

Ibyo byafashije gusobanura impamvu abahanga benshi bavuga ko kunyurwa kw’umugore kudashingira gusa ku burebure bw’igitsina cy’umugabo.

Ubushakashatsi bwa kijyambere bwatumye habaho impinduka zikomeye mu buryo abantu basobanukirwa ibyishimo by’umugore, cyane cyane nyuma yo gusobanukirwa neza uruhare rwa clitoris mu byishimo byo mu mibonano mpuzabitsina.

Impamvu itumanaho riruta ubunini

Abashakashatsi benshi bahuriza ku mwanzuro umwe: niba hari ikintu gifite uruhare runini mu kunyurwa mu mibonano mpuzabitsina kurusha ubunini bw’igitsina, ni itumanaho hagati y’abakundana.

Mu bushakashatsi bwatangajwe muri Archives of Sexual Behavior, byagaragaye ko abantu bashobora kuganira ku byo bakunda, ibyo batishimira n’ibyo bifuza mu mibonano mpuzabitsina bagaragaza urwego rwo hejuru rwo kunyurwa kurusha abatinya kuvuga kuri ibyo bibazo.

Ibi ni ingenzi kuko abantu benshi bamara imyaka bibwira ko ikibazo kiri ku mubiri wabo, nyamara ikibazo nyamukuru kiba ari ukubura uburyo bwo kuganira ku byo bakeneye.

Ingaruka zo kugereranya ubuzima n’ibiboneka muri porunogarafi

Kimwe mu bibazo bikomeye byagaragajwe n’abahanga ni uko abagabo benshi bubaka ishusho y’ibisanzwe bashingiye ku byo babona amuri filime z’urukozasoni.

Impuguke mu mitekerereze David Ley yagaragaje ko abantu benshi bibagirwa ko izo filime zikorwa hagamijwe kwerekana ibintu bidasanzwe kugira ngo bikurure abareba.

Nk’uko filime z’intambara ziterekana ubuzima busanzwe bw’abasirikare, ni ko na porunogarafi idakwiye gufatwa nk’igipimo cy’ubuzima busanzwe bw’imibonano mpuzabitsina.

Iyo abantu bubakiye ku byo babona muri izo filime, bakunze kwiremamo impungenge zitari ngombwa kandi zishobora kugira ingaruka ku cyizere bafitiye imibiri yabo.

Isoko rinini ry’ubucuruzi bushingiye ku bwoba

Buri mwaka, sosiyete nyinshi zinjiza amafaranga menshi zigurisha amavuta, imiti, ibinini n’ibikoresho bivuga ko byongera ubunini bw’igitsina.

Nyamara ibigo byinshi by’ubuzima birimo Mayo Clinic byagiye biburira abantu ko ibyinshi muri ibyo bicuruzwa bidafite gihamya ya siyansi ibishyigikira.

Hari na bimwe byagiye bigaragara ko bishobora guteza ibibazo by’ubuzima birimo gukomeretsa imyanya ndangagitsina cyangwa kugira izindi ngaruka z’igihe kirekire.

Ikibazo nyakuri si ubunini, ahubwo ni icyizere umuntu yifitiye

Abahanga benshi mu by’imitekerereze bavuga ko rimwe na rimwe ikibazo nyakuri atari ubunini bw’igitsina, ahubwo ari uburyo umuntu abyumva.

Mu gitabo Manhood in the Making, umuhanga mu mitekerereze  David Gilmore yagaragaje ko imico myinshi yubatse ishusho y’ubugabo ku bintu bifatika umuntu ashobora gupima, nyamara ubuzima nyabwo bw’imibanire bushingira cyane ku myifatire, ku bwizerane no ku bushobozi bwo kubaka umubano mwiza.

Ni yo mpamvu abaganga benshi bavuga ko umugabo ushobora kuvugana neza n’umukunzi we, ukumva ibyo akeneye kandi akamwubaha, ashobora kugira ubuzima bwiza bw’imibonano mpuzabitsina kurusha ufite impungenge zihoraho ku bunini bw’igitsina cye.

Icyo ubushakashatsi busorezaho

Nyuma y’imyaka myinshi y’ubushakashatsi, umwanzuro wa siyansi urasobanutse kurusha uko abantu benshi babyibwira: ubunini bw’igitsina bushobora kugira uruhare ruto ku bunararibonye bw’abantu bamwe, ariko ntabwo ari cyo gipimo nyamukuru cy’ibyishimo cyangwa kunyurwa mu mibonano mpuzabitsina.

Ahubwo ibintu nk’urukundo, ubwizerane, itumanaho, ubuzima bwo mu mutwe, kumenya umubiri w’umukunzi no kumwumva ni byo ubushakashatsi bwagiye bugaragaza kenshi nk’ibifite uruhare runini.

Mu magambo yoroheje, siyansi ivuga ko abantu benshi bahangayikishwa n’ikibazo kitagira uburemere bungana n’ubwo bagitekerezaho. Kandi uko ubushakashatsi bugenda bwiyongera, ni ko birushaho kugaragara ko ubuzima bwiza bw’imibonano mpuzabitsina budashingiye ku bunini bw’urugingo runaka, ahubwo bushingira ku buryo abantu bubaka umubano, bumvikana kandi bakubahana. Ba uwa mbere ku makuru yacu https://whatsapp.com/channel/0029Vad5UfC89inh67apBK2j
