What's the etiquette in this situation?

[gimmeme]

I've known a guy from out and about the past few years. We recently started chatting and now I'm going over to his this weekend.

I've made it clear I'm interested in purely sex and he seems fine with that. He asked if I wanted to come over this weekend for a few drinks. I agreed.

I don't think I could go and have sex the first time without a little Dutch courage.

But my question is - how does this go? Do I go in and have a few drinks and a chat? Then say we are both feeling it and have sex, how long after do I leave? I don't want to be rude and leave straight away but also don't want to stay etc.

How does this go?

See how it goes? You might want another round? And yeah then just say I've ordered the cab for 11 or whenever.

This!
Also make sure you confide in someone where you are going and let them know when you’re home. Leave a note of the address at home too.
Have fun.

If you find yourself necking Special Brew for some Dutch courage, and throwing up into a bin rather than having a one night stand with someone you really fancy, your subconscious is telling you that you don't really want it to play out like this. That was something my 22 year old self needed to know, and I suggest that your worry about post-sex etiquette may also be your unconscious trying to tell you something.
