Okay, this article has several important points, and one (or all) of them may shock you.
First, and not surprising, sex and exercise are linked. Men who exercise 20-30 minutes a day are less likely to suffer sexual dysfunction.
Second, sex burns calories, more than you think.
“[H]aving sex three times a week burns the same calories as running about 30 miles per week.” (1).
Wow! I hate running, but as for sex, I have a VERY different opinion.
Third, and perhaps the most shocking to some, the context of your sexual act matters. If you engage in sex as part of a monogamous relationship or a casual fling, each has it’s own effect:
“Experts believe that sex in a loving relationship has a healing effect on body and mind, but that promiscuous sex has the opposite effect (sorry to burst your bubble).” (2)
