Or you can make small in and out movements that stimulate the outer part of her vagina. The correct movement in sex depends on what position you're using. A young man emailed: A second man responds: We also do some role play, safe enough within the bedroom, about her fantasy of being taken against her will. That helps you communicate much better. Now that we're in a stable relationship and I'm simply entering her without a condom, I find I can judge the position of my penis in her vagina much better. We started in the man on top position, but I couldn't get the rhythm right, and my penis kept popping out of her. We do this by having her thrust up and down as I penetrate her deeply - this way, her clitoris rubs or bangs against my pubic mound, and she comes quite quickly. We spent so much time trying man on top that it came as a surprise when she suggested that we do something different - it was even more of a surprise when she suggested the rear entry position! You don't have to just stick to one rigid formula when you have sex. To do this, you need to support your weight on your lower legs and arms or hands, so that your pelvis is free to make the thrusting movements which will move your penis in and out. Anyhow, that's a few of the reasons why we like man on top! You the woman have one of his legs between yours and you then grind yourself against his thigh. Are you looking for an effective way to bring your partner to orgasm when you make love? But after we had tried man on top in the dark, we moved to man on top with the lights on, then we enjoyed man on top in every room in the house - maybe that's why it's our favorite!
