Sex by any other name

I tweeted a few days ago about different words for sex. See, a year ago I took a class on sexuality and on the first day, the instructor asked us to shout out any and all words we associated with the word sex. I am posting those here, but I also want to know what words come to mind when you think of sex. Leave them to me in a comment! I'd love to add to my list!

I added:
So, got any more to add? Please Comment - give me any words or phrases you can think of. I would love to hear them all, especially those from outside the US, as I am sure there are some I have heard and many I haven't!
