Okay... thanks.... I knew most of that... especially about the masturbation killed the dinosaurs. I mean everybody knows that...
But what's the downside? Let's say I were to bust loads everyday... Other than the lack of energy and that relaxation feeling:
What kind of "stress?" can you get by relieving stress?
I know the myths... now what's the facts. Arthritis? lol
Busting one load every day most likely would have no effect whatsoever, unless you jerk off for hours straight.
The downsides I would say, like you mentioned, are like that with cannabis: you suddenly lose interest in other things and it might make you lazy. This isn't a concern itself, but might lead to problems.
The effect on your body would (and I'm just speculating) most likely be producing more hormones, thus you would be more horny. Maybe even get restless if you don't get to masturbate. If taken far enough,
You Might get a boner easily, maybe even spontaneously.
It might make you sore too, imagine doing it to any other part of your body, like jerking your finger or nipple every day. Numbness too, becoming less responsive to touching, if the skin thickens or you become "too used" to being stimulated. It would probably take quite an effort though lol.
Apart from that I really don't see any severe issues with masturbation, and I doubt there are any. It's a bodily-regulated process, like producing saliva or taking a piss - you can't control it so it would take quite extreme actions to fuck it up.
