Dear Mr. X,

You're experiencing the height of your sexual life right now, and obviously, such pleasures are hard to give up. But once you find someone who's right for you, you can show her how to please you, if you've been observing the techniques your current girlfriend uses to send you into orgasm orbit (phrase courtesy Cosmo).

However, you don't want a relationship right now. You want to "spread your sperm" around campus. That's good for the ego, but not certain to be so high in the pleasure factor - at least in the sense that empty sex can be kind of, uh, empty. And the thought of another guy getting the lovin' you've been getting is hard to handle. But don't think of your chick with another guy. Think of yourself, free from a girl who you portray as needy, insecure and superficial.

If you two have bonds other than sex, though, maybe you can work things out. Differences between people don't have to stifle a satisfying relationship. But if her response to your attempts to discuss your problems is something as silly as "I like you better than you like me," then it doesn't seem like you're going to be able to solve things as adults (unless, of course, you're able to make her realize how childish she's being).

Sometimes, when I think I don't know what I want, I flip a coin. If, when I look at the result, my stomach falls with disappointment, I realize that I knew what I wanted all along. I'm not saying your situation is something you can solve with a "heads I keep her/tails I don't" deal. Rather, you probably already know what you want to do about your situation. It's just a matter of realizing it to yourself, and ultimately acting upon that decision.
