Do women (or men) gain weight after having s*x?

Question

I've been told from some girlfriends that you gain weight after having s*x. Is that true? If it is, is it because after it, you automatically feel hungry (hence the added pounds)? Or it's just an effect the body takes?

Answer 1

Having s*x....(good s*x) burns a lot of calories, so I have no idea why anybody would say that it causes weight gain. [scratching my head in confusion]
