Don't think about the kids not even for a second. This one's for you, Supermama! Here's why this is so critical, Dr. Parrott explains: "He knows when you are genuinely with him, and when you are merely trying to check sex with him off your list. One word: lube. Lubricant is the little thing that every woman should try to improve her sexual pleasure, and in some cases, even reduce sex-induced pain, says Amy Levine, sex coach, certified sexuality educator and founder of SexEdSolutions. Besides, using a lube can make penetration a lot more enjoyable for both partners," she adds.

You may envy the wild life of young, single men. You might imagine their escapades, that they sleep with a different woman every night. Maybe you remember sowing your own wild oats -- or regret that you didn't sow more while you had the chance. But I have news for you: Research has shown that married men have significantly more sex than their single counterparts.

According to a recent study published in the Journal of Sex Medicine , 87 percent of married men say they consistently experience orgasm during sex. Just 49 percent of women say the same. Some attribute the circumstance to a difference in libido.
