Is masterbating 3 times a day bad? Effect ?

Not bad at all. When I first figured out how to masturbate I was doing it every chance I got, sometimes as often as 10 times a day sometimes I did it so much my penis got sore. I don't recommend that. lol It's actually good for your mind and body as long as it doesn't become an obsession so just enjoy it, you'll slow down after some time. Eventually you'll learn to go slower and take your time so you can enjoy the whole experience more. You have something new, it's normal to try it out and see what it does.

No. Not if you're still able to have active erections, you're fine. Or if it's not getting in the way of other things that needs to be done.

Though, If you're having trouble attaining more than "3/4ths" of a full erection, I'd cut back.

Or instead of cutting back, take cold showers. Cold showers REALLY helps the libido. It's half-way dramatic.

Might be if you are over 60.
