No the analogy goes, when you pick your nose with a finger, you wiggle it around a bit then take it out (in the same manner that a penis goes into a vagina, in, outs, in outs and then shakes it all about)
When you take your finger out of your nose, you nose feels better than your finger ya? (or for that matter, if you were cleaning your ear, your ear would feel better than the finger) Thus, sex is, by this theory
meant to feel better for females than males.
This, of course, is probably rubbish. After all, when you sneeze, what feels better, your nose or the hand that caught the snot?
