<human>: Condense the text into a few key points

The question now seems to have a pretty obvious answer. But I'm serious. I've never been in a committed, long-term relationship. It has turned out to be no more than casual sex with nearly every guy I've seen.

Admittedly, I have had a hard time saying no. The longest I've held out on a guy is a week or two. I have justified this to myself that "with the right guy, it won't matter if I give it up right away. He'll be the *right* one, and will like me for *me*." Plus I put myself in the situation (ie. his house alone) which makes it that much harder.

I'm just done with casual sex. I want to meet someone. I want a relationship. I just don't know how to go about finding one. 

My brother's say to hold out on the sex. They swear by it. I have yet to see if this works (haven't exactly tried it). Is that what it is, though? To simply not give up the goods? Or is there something wrong with me?
<bot>: I've never "held out" on a guy and am wondering if this is why I haven't been in a relationship
