Answer:
Its not bad for ypur health, girl or boy. You can do it as much as you want to.
Seriously? No. It's healthy and normal. As long as that's not all you do all day long and aren't avoiding real relationships.
If anything, it's healthy.
Everyone does it, and it's a normal and natural way to become more comfortable with yourself and 'explore' your body.
So, go for it. Just don't let it interfere with anything important.. or whatever. Haha
No it's not bad for you it keeps things working especially the prostrate.if you are male. I started when I was about seven I am nearly seventy now and I can still get an erection not quite as hard as it used to be but it's there (the heart ain't pumping like it used to). Just enjoy. A slow one with lube is best.It also helps you sleep.
Considering almost every adult in the world masturbates and is still alive and well, I think you can safely assume that masturbation will not harm your health in any way.
It's bad if you rub too hard. You don't want to end up with a cut in your skin there.
Mastubation is healthy as long as it does not interfere with your everyday life.
