I'm just about to turn 18 and the last time I had sex was at the age of around 11-12 (not completely sure, can't remember). So yes, I have had no sex between 12-17. (Likely 18, I'd like to before 18 but It doesnt look likely)

I have had one (not seruious) 'girlfriend' which lasted a month (at 15) and one casual 'fling' in which I got a bj at 16.

But I've had lots of crushes! :D, from the age of about 12 - 13, crushed on one girl, became friendzoned/beta oribiter, but not even that close.

13-16 another crush, asked her out she said no, I used to quiver when she would talk to me even three years on. The imaginary relationship I had with her was more intense than my real girlfriend at time, I imagined us doing everything (and not just in a sexual way ofc).

For about the last year and a half I've been really into this one girl, I pretty much read every fb post she has ever had, but I've never directly spoken to her. I realised how fucked this was and I've detached myself now, especially after walking in on her getting spit-roasted at a party (by accident, im not that creepy). Once she sat next to me and I started sweating beads, thats how much I liked her (and we had never even spoken)

But now there is a new girl, who I really dig and I'm doing the same, I day dream about being with her, I'm a lot less nervous around girls now and I do talk to her on occasions, yet some nerves still come across. Also a few months back there was another girl who I liked, I didnt stalk her as intensely though, but I did read through her twitter/the twitter of a few close friends of hers who I dont know directly, this was ongoing with the 16-17 fixation, though it definitely helped numb it. But the point is I was able to fixate over two people at once.

So I need some help in avoiding oneinitis/fixation over girls who I crush on. Thanks for your help :)
