How do you know you're gay?

For the next few years I had only homosexual relationships and thought of myself as gay, but then I met and fell in love with a woman. It took some time for me to figure out that I was actually bisexual....and even though I’ve been married to a woman for a number of years now, I’m still bisexual.

It's all about what feels right to me. My romantic and intimate feelings goes to a person being my own sex. The opposite sex does not attract me. That was basically, in a simple way of explaining what made me come to the fact admitting to myself that I'm gay.
