I'll maintain it's not a problem if you start going to local munches. It's the best way to meet people, and even among the older people, those people have younger friends.

You might find that at 18, 25-33 is really really hot. I ventured as far up as 40 before I hit 20. It was the best sex (and sometimes kink) of my youth.

P.S. Now... I'm a proponent of "turn-about" is fair play. I have SO much to offer. ;^D
