Women of all ages say they're enjoying sex with their partner more now than they used to, according to a survey conducted by ELLE/MSNBC.com. For many men, however, giving up the thrill of the chase means giving up some thrills in the bedroom as well. A record 77,895 adults took the online reader survey over two weeks in February, answering more than two dozen questions about what works and what doesn't in their sex lives.

Men are bummed because they feel sexually unappreciated. Among men, 53 percent said they felt more desired by their partners in the early days of the relationship. Both men and women reported a drop-off in passion after two years together, but being together a long time doesn't necessarily mean the end of bedroom bliss, even if it means a little less quantity. Even when they do make love, 41 percent of men said they wish it lasted longer. More than two-thirds of all participants said the average sex session lasts anywhere from 16 minutes to an hour, but for almost 20 percent making whoopee takes less than 15 minutes.

Couples who reported good sexual communication and were open to trying new bedroom tricks reported being quite satisfied even decades after they met. Of couples who have been together six years or more, 34 percent said their passion is as strong as in the early days. Even after up to 20 years, one in three couples is still having a fabulous sex life.

The Reasoning: 42 percent of women cited stress or being too busy as reasons why they didn't have sex at one point or another in the prior month. One exception to the overall positive picture for women is the large group -- nearly 25 percent -- whose negative body image prevents them from feeling sexy.
