Questioning your sexuality is an important part of growing up. It's cmpletely normal and healthy. I went through it my first year of college. Out of no where I just started viewing men as a sexual possibility. I started noticing good looking guys and I was quite concerened by how much I thought about it. The worrying about it just made me think about it more, and in turn worry more. Eventually I dealt with the fact that most people have a bit of adrogyny in them, and that it is normal to appreciate beauty in the same sex. Since then I've been totally comfortable and confident in myself as a pretty big hetero

It seems as if you arnt exactly sure about your sexuality right now, but the best thing you can do to clear things up is to realize that no matter what you are or how you feel that you have to accept yourself for who you are. You want to be happy, and you dont have to force yourself into a specific sexual guideline to be happy. To me this mainly sounds like you are just realizing that sexuality isnt black and white. Don't Worry!
