other than not drinking as much, what can you do mentally or physically to fix this?

Try fucking a girl you're attracted to ;)

Viagra I guess.

The more realistic answer is just don't get too shithoused when there is fine females around. Not only will it help you not be a drunk impotent bastard, you will probably sleep with less haggard looking bitches.

1) Concentrate on the titties
2) see 1.
3) ?????
4) Bang away like an armed policeman

here here!!

just let go of your worries and tell yourself how much she enjoys your skills. if u go limp just take a break and lick her clit and finger her till she either cums or is about tooo.....that way if she talks about u and she had a good time, she might realize that u were just nervous but really a good lover.
