When did heterosexuals choose to be straight?

So how do you explain when homosexuals are suddenly no longer wanting to be with the same sex. A situation that occurs regularly, frequently and is well documented.

What made them suddenly unattracted to the same sex?

Are you suggesting in this situation that there is some gene or other environmental factor that causes this spontaneous reversal of attraction? I.e, not their choice.

Your list of possible repercussions can apply to many decisions made which are choices and which an individual still chooses to partake in. Even with the possibility of death at the worst end of outcomes.

Saying it is exclusively beyond ones control whether they are attracted to same sex is really not possible or provable except if we take only feelings into account. Why anyone would make the decision as a choice is their business but I put more weight in it being a choice than anything biological.

First of all, I apologize for the long overdue reply.

Anyway, to address your first comment, my guess would be those people thought that they might be gay/bi and then realized they actually weren't.

In terms of genetics, while currently no "gay gene" has been identified, there are studies that show that there is substantial evidence for a genetic basis of homosexuality.

For the record, yes, I am aware that homosexuality is not the only choice people partake in that can lead to them facing the repercussions I mentioned, but when people make choices knowing that they will be subject to those repercussions, they make those choices anyway because they have a good reason for doing so.

For example, if someone decides to convert from Christianity to atheism, it's usually because they think that atheism checks out more logically than Christianity and they believe that the idea of God existing doesn't make logical sense. In other words, they make these choices for logical reasons.

What logical reason would one have to choose to be attracted to the same sex when they can just as easily choose to be attracted to the opposite sex? What would they get out of being a homosexual? How would they benefit in any way?

Note: I should have phrased my "homosexuality is not the only choice people partake in that can lead to them facing the repercussions I mentioned" differently, since it implies that I think homosexuality is a choice, and I don't think it is.
