Don't be a jackhammer with your penis. Variation is more exciting until the end when a change of rhythm can be disconcerting when a climax is near. When I am moist and you are hard enter with reverence, that first penetration. Feed me slowly and easily. Don't be a fucker.
Fuckers are boy scouts who think a fire is started by rubbing two genitals together at a fast pace.
Don't pull out without warning. I'm not having sex just to make it. I am having sex with you to enjoy it. Orgasm, for both of us, may or may not come. It is silly to go on and on into exhaustion trying to make me cum.
