We are in the EXACT same boat. I'm 22. I've had 5 sexual experiences and I've never been able to come, but the only time it has ever been physically pleasurable for me was after I had been drinking. Is it a bad thing? It can be. At least, to start. I think it's okay to drink and have sex because it loosens me up and relaxes me and helps me enjoy it, and of course I remember it afterward, there would be no point to do it if you won't remember it. But maybe once you become in a stable relationship, start off with the drunken encounters and then ease off into focusing on what makes you tick and exploring each others bodies.

But that's my two cents, considering we are both in the same position. Hope this gives you some ideas.
