Im 15 and i dont think i have many boy friends?

[Demi]

I'm in my last year at high school, and I'm in a small group of 6 friends. There's 3 younger lads who hang around with but I barely talk to because they are sometimes annoying and 3 of my friends suck up to them and flirt with them. One of my friends hated them because they are really immature, I hate them going places with us, but the others always invite them! I don't see what they see in them. They text, flirt, everything!
My friend that hates them just ignores it but I can't! She's more her own person and family orientated so she's rarely free.
I feel like I have no real boy friends!
I feel alone, and I can't leave my friends, obviously I have friends in other groups but I've been with my group for 4 years! I'm not going to leave them now!!
I have never had a boyfriend either :/
I talk to boys at my school, text maybe 1 2 or 3 but I don't think they consider Me a friend? I dunno :/
I'm a sensitive girl so things like this get to me of course but I see girls with boys and I've tried socializing with boys and I do but we don't meet up, I never think they consider me a proper friend, I hate making first moves too!

Sorry this is long but I'm worried people hate me or that I'm unattractive...
I do prefer older boys though yet I've never been out with one. I prefer their maturity and kindness (the ones I've spoke to) like over facebook, and some young male teachers in school.(don't worry I'm not going to try a get with them, I just like their matureness and kindness towards me!)

Anyway, thanks for answering and please read it all! 10 points to best answer!
