Did you ever question your sexuality before this incident? People have the very powerful ability to place ideas about ourselves in our minds that are usually false...if you're truly not gay, why should this be any different? I too questioned my sexuality as a young teen because I mistakenly thought that admiration of other women = sexual attraction to them. It doesn't. I love both my current and former female therapists, and I admire some of the female teachers I've had in the past. I even find them attractive. But I realize that this really is pure respect and admiration rather than sexual attraction. Does any of this sound familiar? Like Lola said, only you can be certain of your sexuality. Don't let this girl get to you - bullying about one's sexuality (gay or straight) is far too common.

Hope this helps
