First, just because a woman is attractive doesn’t mean that someone else is attracted to her in the sexual sense. And just because someone is attracted to members of the same sex doesn’t mean he/she wants to bed everyone within that sex who is attractive. Surely you have male friends who are handsome and nice but whom you don’t want to sleep with. The same holds true for lesbians and gays. Sexual attraction is a personal thing – either you feel it or you don’t. While objective good looks are a good start, at the end of the day, the most beautiful woman or man may not ‘do it’ for me. As for why your friend may not be interested in you, most lesbian women have no interest in being experimented with women by who aren’t clear about their preference. The gay lifestyle is hard enough – why get emotionally and sexually involved with someone who might just be curious?
