Whats most interesting on a woman is dependent on the person interacting with said woman, some like the puss, some like the ass,some like the smile, some like the feet or the tits, e.t.c. As far as position goes once again dependent on woman and the person interacting with said woman. Some prefer missionary, some like cowgirl/reverse cowgirl, some like doggy style, some like the Wobbly H, some like the standing 69, some like the well the list goes on and on and to say that one position is what most people do comes from a very narrow scope of the person determining what the most common position is. I could put the kama sutra to shame but never be able to tell you what my favorite or the best position is, cause truth is, if it feels good it's the best and most used position at the time.
