Sakuni, who the hell are you? you are acting like you know everything. I am not saying you don't but if you are claming about your expretise on mastrubation and saying you've done research then put your credibility. are you a doc? a research scientist working in a research center or a university, or just some jerkoff who surfs around the websites and calling it a ]research. It is better to keep your mouth shut then giving advises. Cuz i am sure people read these kind of messages. Lot of people are struggling with sexual problems and they tend to blam mastrubation. they are confused and do not know what is the truth. They seek advises and if you're gonna provide one, provide valid one and give your credibility so they can trust your points. I think, and i maybe wrong as i have not done any sceintific research myself but read some articles, mastrubation is normal, but over mastrubation is bad. Over means, more than 3 times a week. Specially when you lack sleep and worn your body. Also, watching porn and mastrubation can have serious affect on your mood. You may wish unrealistic sexual favors from your partners as you may see on the porn movies, which your partner may not find appealing. Sex is imporant , do not damage your penis with over mastrubation. Mastrubation is normal but over mastrubation may cuz depression, make your lethergic both physically and mentally.
