Re: how did you know?
I realized kinda late that I was Bisexual, I have never been much of the social kind, never really been in contact with my emotions, Have never really been after a romantic relationship that much. so I really only realized recentlyish(Early November last year) that I was Bi.
Its a bit of an eye-opener. all the discrimination people get for something they don't choose. I never really thought about my sexuality until then.
Well thats my slightly pointless story.
