They also should have mental characters of femaleness because they are under the influence of female sex hormone. Is it a choice, to enjoy eating cockroaches or not?

Scientists find DNA differences between gay men and their straight twin brothers
The other twin did not. Although identical twins are not completely genetically identical and do not share precisely the same environment in uteroneither is sexuality completely genetically determined. Many researchers believe that a person's eventual sexual preferences are shaped in the uterusby hormonal shifts during key stages of fetal brain development. It will have some practical value, for example, in differentiating which member of a set of identical twins matches genetic evidence found at a crime scene.

But experts said the results -- as yet unpublished in a peer-reviewed journal -- offer preliminary new evidence that a man's genetic inheritance is only one influence on his sexual orientation. The study of how people differentiate in their genomic expression is a growing area of research. I edited your question because it was unclear and had been marked for review. Our brains determine not only our sexual orientation, but also who specifically we find attractive, in ways that are complex and fundamentally beyond our control. Many researchers believe that a person's eventual sexual preferences are shaped in the uterusby hormonal shifts during key stages of fetal brain development. Delighting, caught up in her femininity, a woman goes into bondage with reference to men.
