Guys, can you tell if your girl cums? All women are different and give different signs. One girl friend I had, Sylvia, when she came, she got goose bumps on the cheeks of her butt! It was the most amazing thing! They'd appear just as she hit the jackpot, and last for a minute or so. It was a dead giveaway! Of course she had other signs too, like throwing her head back (she liked to be on top) and moaning "OH!" about 7 or 8 times! Her nipples would also tighten up. It was such a thrill for me!
