@Bisougarou:
They tested a drug some time ago that could actually make gay people feel attracted to women (well not really it was just their brains that with some big help make them react about a woman the way they would physically react about a man)
If it really was successful we surely all would have learn about it by now.
So far, none can prove that he/she really manage to change his/her sexual orientations. And simply because people can say what they what they want but we still can't see a feeling. Cause here is the problem : you can stop being attracted to everyone but you can't stop having feelings for someone and that's what define your sexual orientation! Who you fall in love with!
The only solution would be turn into a sociopath : you can't feel love so you won't fall in love with men. But sadly you won't fall in love at all. Ever. Again.
Btw they're still really far from "the gay gene" if it does exist! And i certainly, if it does, that won't find it. Sorry for those, who may want to "change" some day, but if anyone was able to discover before you're even born what your sexual orientation would be… let's just say homosexuality would have disappear many years ago...
Your sexual orientation is not defined by whom you fall in love with. It is defined by whom you are attracted too. By your definition a male bisexual that falls in love with a women is straight and one that falls in love with a man is gay and that is not the case. They are attracted to both sexes and that is what makes them bisexual. The same for gay.
