Bi/pan people ftw! That said, I think it's totally normal and ok to be confused about your dating preference. We live in a society where a lot of people want people to pick one or the other and, often, it just doesn't work like that.
Speaking of attraction, my bf is coming over tuesday and I want to impress him (or whatever the word is for make him think "this guy is fantastic and I'm so glad we're together") while being myself, of course. I also need to relax and not be so awkward. Anyone have any advice?
