When people talk about woman on top positions, they generally mean the woman straddling the male in a kind of “riding” position, also known as “cowgirl”. My wife seldom does that and instead lowers herself completely over me, her chest on mine; think of missionary position with the woman on top. In this position, I can caress and pet her back and buttocks, but otherwise not move much, and it's very clear that the lady leads coitus.
Do you also use this position?
