I am a christian by the overall culture and philosophy I was born into but am an agnostic. When I read (and do a lot) about religion I can't see this omnipotent power being so small and petty in creating anything obedient and ready so suffer. But that is just me... not looking for a debate here!
As for masturbation I think it is a very good stress relief and totally different for the 2 sexes. In young men as JaredR is it is totally normal to get carried away at times and do it so many times a day. For girls it is more a way to discover their own body. Many grown men masturbate even when they have a partner/or regular sex. Women also.. an orgasm is an orgasm, nice sensation to have
so I can't see the wrong or right here except the fact that the young man wants to try to be "strong" for 30 days. I can't see really why just not decide to do it 3 times a week, but this is his decision and his own test of his "character".
