If all he wants to do is ejaculate, then I suggest he insert his manhood into a vending machine. If he wants to have real sex, he has to pleasure both parties involved. The only way to do it is to hit what the nirvana women call the g-spot . I am not a doctor, but I have enough experience to know what works. So listen up boys, because you are about to make your women very happy.
All men know that women have g-spots.
The popular name comes from Dr. G rafenberg, the man who discovered the erogenous zone. It is a nickel size tissue that is located behind the front vaginal wall. The penis is not the best tracking instrument. The instrument that you should use is your index fingers. It is likely that your penis will glide past it.
