NSFW: What are your favorite and least favorite sexual slang terms?

A comment on this question (as well as one from a few weeks back that I can’t seem to find) caused me to think it might be fun to share which sex-related slang terms float our boats and which ones sink them.

Now, I know there are plenty of people that don’t stray from “sex,” “vagina,” and “penis,” but let’s have some fun here.

So, are you partial to pussy, cooter, snatch, etc? How about dick, cock, dong, etc? And what of fucking, screwing, and boning? What terms do you like and which make you cringe?

And for jellies outside of the US, please share some of the terms common where you live. Tallywacker, anyone?
