It's a lonely night, you feel like letting off a little steam so you crank one out and swear you've seen God. With sweat coming from pores you didn't know you had and the feeling of every muscle in your body is incapable of movement, seems not a thing in this weird world mattes. When you don't have a lazy rainy day to quite relax you into an early nap, just put on a little music and give yourself a little work out. Sleep, it's what we do best when we're happy. :)

One reason, in the case of women, is that it promotes their lying down for a while longer and thus increasing the possibility of the sperm getting near the ovum. If the woman get to a vertical position immediately after sex, gravity will work against such an occurrence.

Not only is it relaxing and a tention reliever, you burn lots of calories doing it. I think it's the best exercises you can get. Just as long as you switch positions to work all your muscles!

Because just like any other exercise, you have to put in work which mean energy is lost and when energy is lost you need to sleep or rest to gain it back.

male orgasm requires a lot of energy (to produce and shoot the semen), resulting in low blood pressure and tired feeling.
not sure about females, but ppl here say is relaxes them.

Because of the tension (in the mucles before climax) has been released.
