Estrogen may give women an edge in resisting heart disease that can be caused in part by air pollution, a new West Virginia University study found.Researchers determined that males and post-menopuasal females are more likely to suffer damaged arteries linked to diesel exhaust than women of childbearing age.That coincides with a national study released this year showing older women are at significantly higher risk for heart problems caused by air pollution than other people.
A man usually needs about two or three minutes of stimulation to have an orgasm,a woman generally needs 10 times more. For a man,an orgasm is instinctive.For a woman,it happens only after direct stimulation of the clitoris. A man's climax usually lasts for 10-13 seconds.For a woman,it lasts 6-60 seconds. A man must recuperate after an orgasm but a woman can have repeated orgasms within minutes or in rapid succession. Wonder why a man rolls over and sleeps after? During sex,his body releases oxytocin,a hormone that induces drowsiness.A woman is more relaxed after sex,which is why she wants to talk or cuddle.
