YOUR GOOD HEALTH: WHY IS ONE ‘INTIL’ TW GAY, THE OTHER STRAIGHT?

In a study where scientists looked at the sexual aroal patterns of intil tws wh different sexuali—specifilly, where one was gay and the other was straight—they found that gay tws monstrated more genal aroal rponse to same-sex imag, whereas straight tws monstrated more aroal rponse to oppose-sex imag [2]. In theory, this means two people uld rry “gay gen, ” but both of them wouldn’t necsarily be gay pendg on certa environmental factors. Tw pairs which at least one tw is homosexual were soliced through announcements the gay prs and personal referrals om 1980 to the prent.

Two sets ntaed a pair of monozygotic tws nrdant for sexual orientatn wh the third triplet dizygotic and disrdant for homosexual orientatn.

Studi have shown that intil tws, if one tw is gay (the term “homosexual” is ed clil studi but is nsired offensive, so I won’t e further), then 30 per cent to 66 per cent of the intil tws also will be gay.

GAY PORN'S MOST SHOCKG TABOO

However, an adopted siblg of a gay person is also more likely to be gay (11 per cent one study), suggtg that the faial environment also plays a signifint role. Heterosexual men rpond substantially more to femal than mal, and homosexual men rpond substantially more to mal than femal5, 6, 7, 8; th, on average, genal aroal and pupil dilatn patterns verify men’s reported sexual of all sexual orientatns rpond, on average, wh some level of aroal to erotic stimuli reprentg eher sex.

However, this effect is pecially mon heterosexual women, whereas homosexual women rpond somewhat more to the same sex than other sex.

THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS

The fdg that heterosexual women are non-specific their rpons to mal or femal, whereas homosexual women rpond more to their preferred sex, was nfirmed wh other measur, cludg reactn time, viewg time, nral activy, and thermography of genalia8, 14, 15, the extent that self-reported differenc intil tws’ sexual orientatns are accurate, their sexual rpons will be siar to those of most heterosexual and homosexual dividuals. Hence, male pairs, we predicted that heterosexual tws would show substantially more sexual rpons to the other sex, whereas the homosexual -tws would show more aroal to the same sex. In female pairs, we predicted that heterosexual tws would show siar sexual rpons to both sex, whereas their homosexual -tws would show somewhat stronger sexual rpons to the same sex than the other sex.

SCIENTISTS FD DNA DIFFERENC BETWEEN GAY MEN AND THEIR STRAIGHT TW BROTHERS

Furthermore, if tws’ sexual rpons reflect general sexual orientatn differenc, then their sexual rpons should be siar effect to the rpons seen unrelated heterosexual and homosexual dividuals.

RultsSexual Aroal of Male TwsWe predicted that heterosexual male tws show stronger sexual rpons to the other sex, whereas their homosexual -tws rpond more strongly to the same sex.

Panel A picts 5 heterosexual tws and their 5 homosexual -tws, and panel B picts 94 unrelated heterosexual men and 97 unrelated homosexual men.

SOME RANDOM THOUGHTS ON ‘GAY GENE’ STUDI

Panel A picts 6 heterosexual tws and their 6 homosexual -tws, and panel B picts 123 unrelated heterosexual men and 136 unrelated homosexual men. For tws, penncy of data was acunted for by cludg pairs as a random size imageSexual Aroal of Female TwsWe predicted that heterosexual female tws show siar sexual rpons to both sex, but their homosexual -tws rpond more strongly to the same sex. Their homosexual female -tws also showed genal aroal to the same sex and other sex, each pared wh basele, although somewhat ls so for the latter, p = 0.

Panel A picts 6 heterosexual tws and their 6 homosexual -tws, and panel B picts 77 unrelated heterosexual women and 44 unrelated homosexual women. Their homosexual female -tws also rpond to both sex, but had stronger rpons to the same sex than the other sex, each pared wh basele, p = 0.

GAY MEN TW STUDY

Panel A picts 9 heterosexual tws and their 9 homosexual -tws, and panel B picts 124 unrelated heterosexual women and 103 unrelated homosexual women. For tws, penncy of data was acunted for by cludg pairs as a random size imageA Comparison of Tws wh Unrelated ParticipantsWe predicted that the difference the tws’ sexual rpons is parable to the difference between unrelated heterosexual and homosexual dividuals. In most s, the 95% nfince tervals of heterosexual and homosexual tws’ average rpons clud the means of the rrpondg heterosexual and homosexual unrelated groups (Figs 1–4).

LARGT STUDY OF GAY BROTHERS HOM ON 'GAY GEN'

However, homosexual female tws dilated more strongly to the same sex than the other sex, as pared wh unrelated homosexual women. DiscsnThe prent study suggts that intil tws wh disrdant self-reported sexual orientatns differ their patterns of physlogil sexual aroal a manner siar to unrelated heterosexual and homosexual dividuals. ParticipantsTwsWe advertised for intil tws wh disrdant sexual orientatns via newsletters at UK universi, social media s, onle news s for gay men and lbians, and at three gay Pri ftivals.

Unrelated participantsUnrelated participants took part prevly nducted studi and clud 94 heterosexual men, 97 homosexual men, 77 heterosexual women, and 44 homosexual women wh genal aroal data, and 123 heterosexual men, 136 homosexual men, 124 heterosexual women, and 103 homosexual women wh pupil data5, 6, 8, 33, 34.

Heterosexual and homosexual men and women rated the mols on their sexual appeal, and the three hight-rated male and female mols across all rater groups were ed for the 2-mute vios were taken om a nature documentary for asssg basele genal rpons.

I adm this is my first letter about homosexual, ctuo tws, but I’m gog to take you at your word that you two are happy and that I should supprs the imag that me to md of two sets of brothers who lived together and me to unseemly ends: the pack-rat Collyer brothers and the tw gynelogist Marc brothers.

While the ncept of tw performers is not new to the gay porn world, the Peters tws are notable both bee of the extent of their populary and the thgs they are willg to do wh each other on mera. No dividual gene alone mak a person gay, lbian or bisexual; stead, thoands of gen likely fluence sexual orientatn, a massive new study of the genom of nearly half a ln people human societi and both sex, between 2% and 10% of people report engagg sex wh a member of the same sex, eher exclively or addn to sex wh a member of the oppose sex, the rearchers said.

Ngun reported that studyg the geic material of 47 pairs of intil male tws, he has intified “epigeic marks” ne areas of the human genome that are strongly lked to male dividuals, said Ngun, the prence of the distct molecular marks n predict homosexualy wh an accuracy of close to 70%.
