Every woman's body works the same.
Oftentimes it becomes abundantly clear that a man is touching a woman as if she's his ex-girlfriend, expecting that every woman is wired the same way and wants the same things. In actuality, she's entirely different from the woman you were with before her.
Put away all assumptions. Touch every woman as if she's the first you've ever been with. Explore every inch of her while silently noting what gets a reaction. Ask her about what excites her. Get to know her fantasies, her kinks, and most importantly, her pet peeves. Approach every woman as a fresh, sexy, clean slate and you'll both be satisfied.
