I kind of have two answers for this. With normal civilian girls I would have say doggy position, I love ramming that ass from behind.
With strippers, it would have to be reverse cowgirl, all the strippers I've fucked knew how to pop their booty which led to them knowing how to ride dick pretty well. I must say it's quite a sight watching a stripper ride up and down your cock like a professional.
Most of the normal girls I've fucked didn't know how to ride my dick that well.
My least favorite is definitely missionary, that shit does nothing for me.
What about the rest of you?

Have them wear a mask, then they can face you.
