Since I went to uni a few months ago I've made a lot of new friends, especially a girl in the same flat as me, called Jen. We've pretty much become best friends and do most things together.
Last week I went on my usual weekly trip to the swimming pool and Jen tagged along with me. Everything was fine until we were getting changed after we'd got out of the pool. That was the first time I had seen her naked and I, for some reason felt really attracted to her.
I've been feeling really confused ever since. I've never felt like that about another girl before. I've had boyfriends before so I've never thought about being gay or bisexual. I don't really want to mention this to Jen in case it ruins our friendship.
What should I do?
