Here is another version of a seated sex position. If a man and woman are having sex, seated sex (with the woman on top) can be a great way to give the woman more control and potentially to stimulate her g spot, if she enjoys that (like any other type of sexual stimulation, not all women do).
In this version, the penetrating partner sits on a chair as usual. The partner who is being penetrated sits completely on top and rubs back and forth in more of a grinding motion which can stimulate both the vagina (and again, potentially the g spot area) as well as the clitoris, thanks to the pelvic grinding.
The g spot, in case you weren’t sure, is generally described as the area on the front wall of the vagina (same side of the body as the belly button) about one or two inches inside the vagina.
My drawing of this sex position can be found after the jump.
