Every time a guy hits on me, I feel powerful and it instantly boosts my confidence, but it also makes me feel guilty that I don’t feel the same way towards them.

I’m a 21 y.o. woman. I don’t think I’m particularly attractive or anything, I usually dress up pretty simple and don’t wear any makeup. But for some reason, there’s this trend of different guys hitting on me and most of it happens at the gym. I don’t really get it and I don’t think I send any “available” signals but it just keeps on happening. When it does, I feel like I can take on the world and my confidence skyrockets for a good hour or two. But after that, I start to feel bad because I don’t like rejecting people and I feel sorry for them. It’s a weird feeling and I don’t really know how to handle it.<br>TL,DR: I feel awesome for about an hour after every time a guy I don’t like hits on me, but I also feel bad about rejecting them.
