I voted for my wife. I provide most of her orgasms. She has clitoral and g-spot (blended) and she also has a-spot orgasms as well. The a-spot is also called the AFE Zone. It is the juncture of the vagina and cervix on the front side. It stands for Anterior (front) Fornix (juncture) Erogenous zone (spot). Google it to find out more.
There is another spot we hit sometimes called the PFE Zone. It is simply 180 degrees from the s-spot. It is the Posterior Fornix Erogenous Zone. My wife can orgasm from stimulation there as well - we just don't do it often.
i tend to get off more easily when my partner is involved, and i've reached an orgasm from them preforming oral or clit stimulation, vaginally and also with my g-spot. When i get myself off its usually through clitoral stimulation or with a g-spot rabbit toy.
