I can understand alcohol to enhance sex, but I would not want to be falling down drunk and do it. As far as drugs, I have heard of people using weed to enhance, but that is not something I would be comfortable doing. I think you should have somewhat of a clear mindset when having sex, especially if you are in the single scene, where you may not know the person very well yet. I think the drugs would have very negative influence on the decisions you would make (same with alcohol).

Using any drug to enhance sex is a taint on making love .. you should try more forplay get youself and partner to the point where you cant control yourself and see what that does to the exp.

I've had all kinds of freaky circus sex on all kinds of drugs, but that was before I had children, wasn't a regular occurrence, and nothing I could recommend to anyone with a clear conscience...least of all outside of a safe relationship, but the legal exposure alone should be reason enough to avoid it. Being arrested for drugs can seriously ruin your life, and being arrested for "hard" drugs is a felony in every state regardless of quantity or intent.

A bit of alcohol (hardly anything) makes me funny, and it's cute sometimes for sex. However, too much makes me fall asleep.

Vamp blood? Ok I watched too much True Blood lol..

Well I tried a lil' bit drunk sex with my ex, it wasn't that great.. I think it's best if you have a clear mind and able to feel everything and "be there" in the moment. Just light some candles, close the doors, roll down the blinds, and do it tantric style the whole night. Who needs substances? :/
