The "X" Position

How to do it.  You sit on the bed with your legs in front of you;  She straddles your torso. 

Difficulty: 3
Payoff:  7

This position allows more gentle rocking than in-and-out thrusting - a change she will love.  Some guys are not going to want to hear this, but a lot of women find powerful thrusting distracting and simply prefer to be "filled up" while they concentrate on stimulating the clitoris.

To make this position really rock, hold hands with each other and lean back so you are connected only at the hands and genitals.  Concentrate on wriggling the base of your penis against the upper part of her vaginal opening, grinding against the clitoris.

What' in it for you:  Since there is little steady motion to wear you out and only  moderate stimulation to the head of your penis, you should be able to last longer than usual.  Once she has had her fun, switch to a position that hits you in the right spots.
