okay I need help.

Autumn💛
So I'll be 15 later this year.  Anyways, lots of guys seem to like me, and some are really great but my problem is that they are always either sweet but all talk and no do when it comes to intimate stuff, or just want me for my body, or they are sweet but I don't feel a connection. And I don't know what to do because there's a guy that likes me and he's my ex, he's a great guy and really likes me. And his twin brother also likes me but I don't like his mmm as much. And then there's this guy who likes me and I like him a little but I think he wants to fuck and idk (I'm a virgin) and idk if I want to lose my virginity yet, and then there's the fact that I just broke up with my ex girlfriend (I'm bisexual) because I have major commitment issues and when I see something not lasting I immediately leave. The point of this is that I really don't know what to do about any of theses people and idk who I want.
