10 things you didn't know about sex

1. The typical lovemaking session lasts around 15 minutes: roughly 10 to 12 minutes of foreplay and around 3 to 5 minutes of intercourse.

 

2. Humans aren't the only horny members of the animal kingdom doing it just for fun. Dolphins and a type of chimpanzee called the bonobo have also been observed engaging in sexual activity when they are not in their natural reproductive cycles.

 

3. While Viagra has made erectile dysfunction (affecting 10 to 12 percent of men) a household phrase, the opposite problem -- premature ejaculation -- is more common (affecting 24 to 27 percent of men). The U.S. Food and Drug Administration is currently reviewing a drug called dapoxetine as a cure for this problem.

 

4. Crank up that thermostat.. . orgasms may be more intense in warmer conditions. The degree of vasocongestion, reddening or darkeing of the skin known as the "sex flush," is both more common in warmer temperatures and an indication of how intense an orgasm may be.

 

5. If a woman experiences orgasm during sex, she is more likely to become pregnant, since orgasmic spasms in pelvic muscles help move sperm up the vaginal canal to the uterus.
