Masturbation: 5 Things You Didn't Know (cont.)
Unlike sex with a partner, masturbation can't give you a sexually transmitted disease. Nor will it subject you to the muscle strains, pokes in the eye, and awkward moments that can come with partner sex. But masturbation safety isn't guaranteed. "Masturbation is just about the safest sex there is," says Cornog. "But the laws of physics and biology don't stop operating just because someone is masturbating."
Frequent or overly vigorous masturbation can irritate the skin of the penis, as the average guy knows all too well. Less well known is that habitually masturbating face down -- for example, by thrusting against a sheet, pillow, or even a carpeted floor -- can injure the urethra in such a way that urine exits the penis not in a stream but in a hard-to-control spray. Barbara Bartlik, MD, a psychiatrist and sex therapist in New York City, says she's seen facedown masturbators with urethral trauma so severe that they are no longer able to use a urinal and must urinate while seated.
In certain extremely rare instances, masturbation and partner sex alike can cause penile fracture. This painful condition -- actually a tear in the tunica albuginea, the whitish tissue surrounding the penis's spongy layers -- occurs when an erect penis strikes a hard object or is forced downward. A medical emergency, it often necessitates surgery.
3. Solo sex can supercharge your sex life -- or scuttle it.
For various reasons, solo sex can be a real boon to sex with a partner. It helps teach men about their own sexual response -- what feels good to them and what doesn't -- so they will be better able to explain to their partners just how they like to be touched. It helps men learn to recognize the "moment of inevitability" just before orgasm and helps teach them how to avoid premature ejaculation. Perhaps most significant, it's a great coping mechanism for any man whose partner is temporarily unavailable for sex -- because of absence or illness -- or has a sex drive that doesn't quite match his own (something sex therapists call a disparity in frequency preference).
Of course, some men become so obsessed with solo sex that they begin to lose interest in having sex with their partner. The resulting hurt feelings and alienation a partner feels can make it hard to sustain the relationship. But experts are quick to point out that masturbation is perfectly OK even for men in a committed relationship. "We cannot assume that just because a man masturbates that there is a problem with his primary relationship," says Bartlik.
4. Certain forms of masturbation can lead to sexual dysfunction.
Experts warn that men who frequently stimulate themselves in ways that don't simulate sex with a partner -- for example, stroking very rapidly or with great pressure or friction -- can develop retarded ejaculation. That's a type of sexual dysfunction in which it is difficult or even impossible to climax during partnered sex. "Any man experiencing any sexual dysfunction should ask himself if he's masturbating in ways that produce sensations that differ from those he gets from his partner's hand, mouth, or vagina," says Michael A. Perelman, PhD, clinical associate professor of psychiatry, reproductive medicine, and urology at Weill Cornell Medical College in New York City and the president of the Society for Sex Therapy and Research "Then he should consider what he could say to her to make the stimulation more similar -- and how he could change the way he masturbates to make it feel more similar to what his partner does."
