Actually no, I don't love the Bible. I know why you assumed what you did, but I am not a Christian. I'll forgive you for that..
Masturbation from a physical standpoint is NOT as healthy as the medical establishment makes it out to be. For those over 40, yes, they should flush the pipes because the prostate is not as flexible as it once was, but for men under that age there is absolutely nothing unhealthy about celibacy or sexual restriction. Semen is the most valuble physical essence of your body.. the only tissue it has more in common with is neural tissue (the brain). It contains a lot of vitality.. it has to, what with its job to create life n all. If you constantly masturbate or release, you drain yourself of vital chemicals.. for the woman this is great as she absorbs it all through her vaginal walls, but for the man.. they don't call it the "little death" for nothing you know. Constantly draining yourself of those vital chemicals puts a strain on your body because semen production is the culmination of your inner alchemy/body process.
That is only physically. Mentally, masturbation is not good for you. Just ask the 1 in 2 males over 40 who suffer ED or sexual dysfunction. That is all caused by masturbation being the primary sexual association in their minds, instead of their partners vagina. In simple terms, they can't perform because they love their hand more.
You can believe the medical establishment and psychological establishment if you want, but I'd rather come to my own conclusions than trust them to be honest. Why? Because they ARE an arm of the Establishment, they want people to masturbate all the time because it makes people more placcid and easier to manage socially. It's the same reason why they allow homosexual rape to occur in jails.. they'd rather keep the inmates placcid than incur a riot because they haven't been able to fulfill their mental associations.
Masturbation is not a sin, but it isn't healthy for you. That's all.
