Yes, you read right. Men have what many sexperts describe as the male equivalent of a woman's G-spot, and few males are even aware of this pleasure zone in them. It's called the prostate, a walnut-sized gland surrounding the urethra which creates the fluid secretions in semen. And when stimulated right, it is capable of giving your man explosive Os.

Hot move to try: Wrap your hand around his erect shaft and then move it toward his body instead of the usual up-and-down motion. Manually stimulating his penis this way causes its erectile tissue to press against the prostate (which lies just behind). You're basically stimulating his two hottest spots at the same time!
