if you honestly can't force your dick to get hard with someone you have no attraction towards you might want to schedule a doctors appointment because you should be able to

Uh, right. Because it's healthy to force yourself to be aroused with someone you're not attracted to. Frankly I've been in situations like that and no, I couldn't get hard - and no, I don't have any medical problems. I have plenty of sex with someone I am attracted to. Dickwad.

That person is bisexual at the very least regardless of what you think. If you're out there having sex with men and you're a man, you're gay. If you're out there having sex with women and you're a man, you're straight. Do some of both and you're bi. You can say innate attraction is that only thing that determines hetero/homo-sexuality, I think that's bullshit - and I fully support gay people, I'm not some religious gay-basher. I just think it's a shit cop-out bunch of wussy lies. Choice is everything in life, and you can choose anything you want. People choose to have their dicks cut off to become transsexuals, for godssakes. Initial attraction may be a factor in everything, but ultimately it's all about what desires you choose to feed and grow that determine who and what you are.
