Making love could be one of the few pleasures in life that is genuinely good for you, say researchers.
If you have money to lose in a casino, you will probably have enough for a young girl offering her company to wealthy tourists.
Those who had sex three or more times a week lowered their risk fourfold.
As women get older their oestrogen levels drop, says Dr Peter Bowen-Simpkins, consultant gynaecologist at the London Women's Clinic and spokesperson for the Royal College of Obstetricians and Gynaecologists.
Only last month, researchers at Nottingham University concluded that men who kept up a regular sex life in their 50s were also at lower risk of developing prostate cancer.
(Conversely, they found 'too much' sexual activity - more than 20 times a month - in the 20s and 30s could increase the risk.) In fact, the research seems to suggest that men - particularly older men - benefit the most from healthy effects of sex.
