Why should it matter if it was a choice. Is it more noble if it was thrust upon you and you had to cope as best you could. Is it that if it were a choice that it would be something you could reverse. It's probably a little bit of nature to a little bit of nurture, the exact formula being unquantifiable and also largely irreversible. People don't generally change, and even less so after a formation of sexual identity.
As long as you can trump the basic human group dynamic of pushing away those that are 'different' intellectually, you're good.
