Curious?..

So I've always been a little curious on whether or not I actually like girls. I find them very attractive and get turned on by them but I can't imagine myself ever having sex with a girl. Making out? Yes. But sex? No. I've only ever dated guys and I'm in a serious long-term relationship right now with a guy and I don't plan on experimenting or anything unless we break up (but I hope we don't). Anyways it doesn't really matter what I am. If I'm straight, bi, pan, etc. Idk but I've just always wondered...
