<human>: So yeah. I've never been entirely sure of my sexual orientation. I've primarily had crushes on girls growing up, but I have had a crush on one guy. Sexually, I find myself attracted to both men and women, and I fantasize about both. I mostly find that I don't know how I feel about a person until I get to know them a bit, though. I've never had many guy friends and the guy friends I do have are gay, and I've only ever been on one real date with a guy, so I have no idea what I am. I've identified as lesbian in the past but I've never felt 100% comfortable with the label. 

Anyway. I just met this guy at school. He's really friendly and nice, we have a lot of the same interests. We haven't hung out much but sometimes if we happen to be in the dining hall at the same time we'll have lunch together. He's also pretty hot. He asked me out, and I'm not entirely sure how to proceed from here. I don't know how I feel about him. I find him attractive although I'm not sure that I'm attracted to him, and I feel kind of nervous about him and I'm not sure if it's in a good way or a bad way. I think more than anything I just feel uncertain. Maybe I'm overthinking it. 

I'm not sure what I should do. Is it better for me to give it a chance and let him know if things aren't working out? Or should I just tell him I'm not interested? I don't want to lead him on, but I really am curious and I want to give it a shot. I just don't want his feelings to get hurt if things don't work out. As a girl who likes girls, I know all too well what it's like when a curious girl wants to experiment but ends up not liking it.
