Going through a dry patch, help me?

I've been sixteen for almost a year now, which means of course I'm almost seventeen. During the past year I've had two girlfriends, one of them was quite a short relationship only lasting a month and the other took up another ten months. It's been a month since my last girlfriend. My girlfriend's were a very y couple of les and I'll admit I'm not the most gorgeous guy out there, but I've roped in some good looking girls so there has to be something about me. I've been told I look like Zac Efron by a lot of people. Anyway, I haven't had since my last girlfriend, and it's been a month, and I'm gagging for it. What shall I do? I've spent nights out in the town, but for some reason it just ain't working?
