I'm with amp...it allows me to relax.

scientific testing has proved masturbation / sex is good for active people especially in releaving tension , if you are getting adverse affects see a doctor

If it weren't for masturbation, I'd have destroyed an entire third world country with my bare hands by now.  It really mellows me out.  Masturbation is God's gift and it's a slap in the face if you refuse this gift from him!

I'm sorry I can't read this thread, i went blind.

It's also God's practical joke to those born without any arms.

So I guess having sex is bad too

Here's the educated response from someone who has taken several bio and psychobio classes.

Masturbation for males reduces testosteron and increases estrogen. A good balance keeps you looking young, less body hair, and reduces baldness. It also reduces aggression and keeps you thinking clearly.

Masturbation in females makes them more confident and more aggressive. Women who masturbate or have a lot of sex are often more dominant and more assertive as it brings them into a better balance.

boxers and other people who are into accomplishment "hold off" because it increases testosterone, which has a variety of effects including less pain, better endurance, sometimes more focus.

Female boxers are encouraged to get as much sex as they can because it increases testosterone.

so then its recommended that a male doesn't masterbate then?

if you compete in sports and other aspects.

It depends what is important to you. If competition is most important to you, then don't. If control over your emotion and thought process is, do.

There are pros and cons to each.

Most that do stay looking younger for longer.

That's BS. 

My favorite line was (paraphrasing) " it is reccomended that females masturbate as much as possible b/c it increases testosterone". 

Apparantly prof likes his women with mustaches and giant sized proportions.
