Intercourse versus masturbation

Men who are very sexually active in their twenties and thirties are more likely to develop prostate cancer, especially if they masturbate frequently, according to a study of more than men. Most of the differences were attributed to masturbation rather than sexual intercourse. The study, led by the University of Nottingham, looked at the sexual practices of more than men who had been diagnosed with prostate cancer before the age of 60, together with controls. Men who took part in the study were asked about all aspects of their sex life from their twenties onwards, including how old they were when they became sexually active, how often they masturbated and had intercourse, how many sexual partners they had had and whether they had had any sexually transmitted diseases.

We confirmed that the volume of seminal plasma, total sperm count, sperm motility, and percentage of morphologically normal spermatozoa were significantly higher in samples collected at intercourse than masturbation, as reported previously.

No contest. A woman can sometimes punch around in the dark and hit the bulls-eye, but I own the equipment and wield it like a Jedi lightsaber. Are you kidding? My hand never ruins the mood just by existing in the same room as me, so the orgasms are always better with my hand.

Now scientists think the two phenomena might be linked. Following orgasm, the hormone prolactin is released into the bloodstream in both men and women. The hormone makes us feel satiated by countering the effect of dopamine, which is released during sexual arousal.
