Most baby boomers think they've learned just about all there is to know about sex.

And, according to a new Associated Press-LifeGoesStrong.com poll on the subject, more women than men are confident of their knowledge. Among people aged 45 to 65, 59 percent of women think they know all about sex, while just 48 percent of men share that confidence level.

The new poll also found that among those aged 45 to 55, nearly half the men _ 48 percent _ complained that their partners don't want to have sex as often as they do, while just 13 percent of women in that age group say the same.

The AP-LifeGoesStrong poll also found that overall, 28 percent of men and 21 percent of women in the baby boom generation are dissatisfied with their sex lives.
