MASTURBATION:
You don’t have to have a partner to enjoy the calorie-burning effects of sex. Masturbation can burn up the calories, as well. You can lose between 100-150 calories for each act of masturbation, according to the Young People’s Reproductive and Sexual Health & Rights Organization. You can raise that amount to around 300 calories, though, through a 5 minute vigorous masturbation session, according to Japanese scientist Dr. Shukan Tokuho.
ORAL SEX:
15 minutes of oral sex can burn off the calories consumed in a long sip of wine. There are calories present in semen, though, so if you swallow, there are around 7 calories in a teaspoon of semen. Since the average volume of ejaculation is 1-2 teaspoons, you can expect an average of 7-14 calories per ejaculation. That will easily be burned off during the course of your lovemaking, though.
