Quiz: Things Men Can Stop Worrying About in Bed

Every woman is different, of course, and many male models and actors bare hairless chests. But some women actually prefer a manly chest of hair.

Women in one study rated men with chest hair as having more sex appeal.

In one survey, only 1% of women said penis length is "very important." Only 20% even rated it "important." More than half said it didn't matter at all.

Width didn't matter to them, either. The same survey found that only about a third of women called penis girth "important."

That's almost double its soft average length of about 3.5 inches.

Studies show that many women do not mention orgasm when asked about their most satisfying sexual experiences. Instead, they talk about feeling loved, passionate, happy, aroused, erotic, and connected to their partner.

In a major survey, people said having sex while using condoms was just as positive as having sex without condoms. Condoms also didn't affect whether they had an orgasm.

That percentage rises to 34% of married men in their 60s, and 54% of those in their 70s.

That was the average in a study of 500 couples from the U.S. and four other countries.

Doctors sometimes also prescribe the "pause and squeeze" tactic. To do this, a man either pulls out or stops touching his penis when he's about to ejaculate. He then squeezes the tip of his penis.

Wearing a condom also can increase the time it takes to ejaculate. And some sex therapists recommend having sex more often as a way of making a man's body more in the habit of sexual pleasure, which may help.

When you add all kinds of cases, mild to severe, many men have erection issues at some point. In one study, that happened to 52% of guys sooner or later. Most cases were not severe.

Erection problems are often linked to age. For example, they're more common at 70 than at 30. But erection problems are not a routine part of aging and are less likely in men who don't have high blood pressure, diabetes, or heart disease, and who manage stress and emotions well.

Occasional misses happen. Things like being very tired or drinking too much can make that happen. But if a man has persistent erection problems over three months, he should check in with his doctor.

Studies have not linked moderate drinking and erectile dysfunction. Drinking too much, whether it's just one night or part of a long-term pattern, can slow or spoil an erection. 

Older guys tend to have more trouble with alcohol's effects on their erections. Men taking medication for ED should get a doctor's advice about drinking.

Reasons for this can include lower levels of testosterone, side effects from some drugs, and health problems. However, there is no age limit on having a satisfying sex life.
