You Won't Go Blind

It's something people don't talk about, but almost everyone does it: masturbation. In one national study, 95 percent of men and 89 percent of women said they had masturbated.

"We are programmed, as best we know, to need orgasms," says Gloria Brame, Ph.D., a clinical sexologist in Athens, Ga. "It's a fundamental aspect of men's health, right up there with brushing your teeth." And the more you know about what satisfies you solo, the more pleasure you get from sex.

You likely know that a little wanking won't make you go blind or cause your penis to fall off. (Let's face it, you'd know by now.) In fact, a little time alone is perfectly healthy for you.

How to Last Longer in Bed

You’ve tried crunching baseball stats. You've mentally replayed your last round of golf. You've outlined the steps to making your favorite sandwich. But the more you try to last longer in bed, the faster you finish—and you’re not alone.

“Premature ejaculation is a problem that affects almost every man at some point in his life,” says Thomas J. Walsh, M.D., a urologist at the University of Washington.

Dr. Walsh says there are primarily two methods if you want to last longer in bed: physical and psychological treatments. While physical remedies target the sensations you feel during sex, psychological solutions address your worry, stress, or other mental factors that may explain your quick trigger, Dr. Walsh explains.
