How can I get over the fact that my crush has had a previous sexual experience?

*This is JackFinch's friend, so don't go calling him gay and stuff*

So I'm in my last year of high school and I like this guy and he's really hot and cute and smart and nice and stuff, but... he's, at the very least, done stuff with a past girlfriend.

Just FYI, he's been through like a bazillion girlfriends back in his immature days, and one of them always ends up sucking her boyfriend's d**ks. All of them. And that's the only sexual experience he's had... that I've managed to dig up (JackFinch did some poking around for me, and that's all he could find too, and he's pretty good!).

I've never had a real boyfriend. I've gotten as far as little kisses and stuff, but I've never given head! And I just can't get over the fact that he's gotten it in the past. It's frustrating, because I really, really, really like him! :\

It's not that I think I'm going to be inexperienced and unimpressive to him because of that. I can't explain it. It's like... I feel uncomfortable knowing that somebody else has done that with him.

What do I do? I really want to get past this, but I get emotional and obsessive over the littlest things.

Help, please!

Thanks, guys. :) :) :)
