Premature ejaculation (the inability to wait with ejaculation for both partners' enjoyment) is another major troublemaker for men. In addition to the "squeeze technique" — in which pressure is applied to the penis, where the glans meets the shaft, on the brink of ejaculation — some drug therapies have been used successfully, such as:

• Selective Serotonin Reuptake Inhibitor. This class of antidepressants is blamed for negative sexual side effects, but sometimes the problem can be turned into a positive by delaying ejaculation until it's desired.
• Tricyclic antidepressant. The drug clomipramine has been shown to be effective in delaying ejaculation, but side effects including dry mouth can occur.

Ways to Treat Women's Dysfunction
Non-drug treatments are often effective for women suffering from sexual dysfunction. According to Alan Altman, M.D., author of UpToDate.com's "Treatment of Sexual Dysfunction in Women," these steps might return sex that's a pain into a pleasure again:

• Have More Sex. "Use it or lose it" also applies to sex — with a partner or alone, sexual activity can increase blood flow and improve vaginal health.
• Communicate Sexual Preferences. Respectfully communicating with your partner about personal sexual turn-ons and turn-offs can work wonders for mutual sexual satisfaction, as can changing up the routine once in awhile in terms of time, location or sexual position.
• Add More Pre-Sex Stimulation. More stimulation by hand or mouth can help the female's sexual response (as well as helping with the male's erection). Ask your partner honestly if you want a greater fix of foreplay.
• Make Healthy Lifestyle Adjustments. Stay hydrated, quit smoking, and undertake strength training and aerobic exercise to up stamina and improve sexual satisfaction.
• Strengthen the Pelvis Floor Muscles. Vaginal weights, inserted and held in the vagina to improve muscle tone, can help some women with orgasmic disorders by helping awareness of sexual response and, in some women, stopping bothersome urine leakage during intercourse.
