there are a lot of really confusing sexualities. you could be heteroromantic, meaning you are only romantically interested on men, but homo- or bi-sexual, implying you are sexually attracted to women. i don't even bother to label myself anymore; i like who i like and that's the end of that. f you are worried your friends will think you are going to start hitting on them or something, try testing the waters. find a tactful way to ask what they feel about that kind of thing, and start sharing your own beliefs in a subtle way. work your way up to telling them. if after you do, they still think you might hit on them, let them know that you've always been this way, and you never hit on them before. make a joke of it if you can ('oh come on, they aren't that attractive') or something similar. if they can't accept this part of you, then they can't accept all of you. it's harsh, but true. being different isn't easy, but it's not a bad thing either. good luck.
