My wife has clitoral, g-spot, a-spot and blended. Blended is when clitoral orgasm is combined with g-spot or a-spot orgasm.

Flawless - the a-spot is the junction of the vagina and cervix on the front side - you can get more info with a simple google search.

My wife prefers stimulation here to even her g-spot. The PFE-zone is 180 degrees from the a-spot making it the junction of the vagina and cervix on the backside. She likes stimulation there as well - but I can't recall it resulting in an orgasm - but as mamy orgasms as she has, its entirely possible. less
