With women:
The girl, who thought that she was clever, told me "afterwards", "You really ARE a cunning linguist." I was taking two different languages at the time, so she thought she was a riot.
With men:
The first time I ever gave head, my friend told me, "If I didn't know you, and KNOW this was your first time, I'd swear you were a pro."
So, I'm guessing there's some instinct there.
Also, I'll answer the question about giving or receiving. If I HAD to pick... well, how about you just lay back and relax for a bit. :tongue:
