Find gay male twins and triplets
A growing amount of research suggests that sexual orientation has a genetic basis. In fact, scientists recently identified two specific genes that appear to differ between gay and straight men . If sexual orientation is indeed genetically determined, it would be tempting to assume that identical twins would always have the same orientation, right? If they have the exact same genes and our genes control our sexuality, this would seem like a pretty logical conclusion. Identical twins sometimes have different orientations. For example, one may be straight while the other is gay.

Title: Homosexual Orientation in Twins: A Report on 61 Pairs and Three Triplet Sets
Why Do Some Identical Twins Have Different Sexual Orientations?
Dear Dr. Roach: I read your recent column regarding identical twins where one of the two was balding while his twin was not. Within my extended family, there are identical twin brothers, who also were almost impossible for family members to differentiate. As such, trying to identify a single cause of sexual identity, genetic or environmental, is not going to be successful. With increasing recognition that people do not fall into binary categories, we can see the limitations of studies that have attempted to answer your question.
Lesslie Polinesia. Age: 23. Hello there I'm standing aline staring at my surroundings, but my mind keeps drifting back to how good a man is when we are together. It's the simple things about man that turn me inside out; but, when we kiss, I burn raw... deep down inside. I crave that next kiss; the one that always leads to more.
Your Good Health: Why is one ‘identical’ twin gay, the other straight?
Twin pairs in which at least one twin is homosexual were solicited through announcements in the gay press and personal referrals from to the present. Thirty-eight pairs of monozygotic twins 34 male pairs and 4 female pairs were found to have a concordance rate of Twenty-three pairs of dizygotic twins were found to have a concordance rate of In addition, three sets of triplets were obtained.
But experts say the origins of partner preference remain a mystery. For men, new research suggests that clues to sexual orientation may lie not just in the genes, but in the spaces between the DNA, where molecular marks instruct genes when to turn on and off and how strongly to express themselves. That news, presented at the meeting of the American Society of Human Genetics on Thursday, may leave the genetically uninitiated scratching their heads. Through the epigenome, the results suggest, some facet of life experience likely also primes a man for same-sex attraction.
