When a man first starts growing sexually, he will probably be rather heady. He exerts effort from his head. He tries to breathe right, remain conscious, and stay present with you, all from his head. Nothing brings a man into his body faster than a warm, wet, wrap of his root. There are certainly times for motionless loving and gentle touch, but there are also times for a healthy grasp with your vagina, mouth, ass, or hand.
Most women touch their man's genitals too lightly, too hesitantly.
Grab him firmly and really pump him. To prevent a premature ending to the sexual occasion, remain sensitive enough to slow down or stop the stimulation before he ejaculates, and then rev it back up as his penis begins to soften. Create an arc of energy between his head and genitals so that his heart is aroused. Remember that it takes great practice for most men to open their heart while having sex. You will only open his heart as wide as yours.
