Regular sex sessions have several health benefits.
A new study has suggested that making love twice a week is as important for a person's health as quitting smoking or cutting down on alcohol consumption and lowers the risk of suffering a heart attack.
Geoffrey Hackett, a professor of men's health at Aston University in Birmingham, said: "We estimate that 20 minutes of sexual activity in a man is the equivalent of walking a mile, and that's a reasonable amount of physical effort if you do it often enough.
"I'd suggest men and women aim for some kind of sexual activity twice a week."
Professor Hackett has argued that doctors should be telling patients more about sexual activity and claims that prescribing it could save lives.
He explained: "Sexual activity is something we rarely discuss, yet knowing if a man has regular erections tells me an awful lot about his health."
