Bisexuality Support Group
Bisexuality is a sexual orientation which refers to the aesthetic, romantic, and/or sexual attraction of individuals to other individuals of both their own and the opposite gender or sex. Most bisexuals are not equally attracted to men and women, and may even shift between states of finding either sex exclusively attractive over the course of time.
And yeah, I agree with chichadee. I think it's always been the underlying motivating factor for me, it's about who a person is on the inside and what resonates for you about a particulary personality.
So I think that I might not be drawn too closely to someone who was very overweight because I enjoy (trying) to keep fit. But if there were other things I was drawn to in that person, their weight would not be an issue. Beauty is in the eyes of the beholder.
And to want to be somebody's friend, that in itself is a beautiful thing because that person is saying, "Hey, I like what I see in you as a person!"
