I really enjoy giving a woman a full nelson. In case you don't know what it is, it's when she leans her back against your chest, and you use your arms by wrapping them around her legs while she leans back against you and you put your hands just behind her neck. It's fantastic. The women I've been with, both aggressive and submissive types sexually, lose their minds in ecstasy from it. It's great. The women I've been with have said it's a very primal kind of masculine domination and the feeling of being sexually subdued is amazing. I've always been told it's pretty comfortable for the woman just so long as she is flexible enough. She is able to see the cock going in and out and they say that being able to see that, the penetration and the thrusting in and out with their own eyes is mind boggling. It's my favorite position. It's a bit more difficult if the woman is voluptuous, but in my experience that depends on the mans strength to hold her up and the size of his dick.
