Homosexuality and heterosexuality are cultural constructs, but sexual attraction isn't (although its expression can be culturally influenced and mediated.) I think what's being presented here is a false dichotomy - after all, closeted gay people don't become straight because they choose to act straight.

To me, you can choose to act "gay" (whatever that entails) but but to be gay or straight isn't a choice. However, sexuality may be more fluid than many people realize, and this realization and the process of sexual self discovery, may appear to be choosing one or the other, because our society requires that it be one or the other.
