Yes of course. I masturbate. I always don't understand it when people condemn masturbation and term it demonic. I self-service three-four times in a month and I don't think there's any demon in me.
Masturbation can only be harmful when people get overboard with it to the extent that it affects their psycholog, general happiness and ability to properly function in the society. There are times when the feeling to get laid gets to me and when there isn't any available babe around, I say to myself, “Bro, you have got to relieved yourself" and usually, once I do that, I always end up being okay for the next five-seven days or more.
For what it's worth, during my university days, masturbation saved me from numerous temptation from girls who usually troop into my room to charge their phones and collect latest movies from my laptop.
