Wait, how did you date straight women as a female?
Anywho, I never thought about sex as a base for attraction. I would be attracted to anyone who is funny, nice, active, and smart. However, I do think that your gender can affect what personal qualities you find to be attractive. For example, my girl friends don't like guys who like video games, but my guy friends drool over a girl who can play them.
In short, gender isn't a quality to be attracted to, but gender can affect what you find to be an attractive quality in a person.
