Never had a boyfriend

I'm 19 and have had sex with so many guys I've lost count. I've had flings with guys but have never been in a real relationship. I want to be so bad, but I think part of the reason is guys think I'm a slut and most guys want a virgin or a girl that's only had sex w 1 or 2 guys. Please tell me I'm not the only one that's never had a boyfriend at this age
