Why everybody lies??

First of all its great to see people who are feeling the way i have started feeling. Finally i can talk and share with some good people:) I am 22 years male. I started masturbating when i was may be 11 or 12. And i ''over did'' it for a long long time. All this while i knew i was doing wrong.But could never resist the urge to masturbate, for more than a week or a few days more than this. Felt, but never gave importance to what side affects of it i was feeling. Low self confidence, finding it difficult to look into eyes, weaker memory and brain, weaker erection, discharge of semen, laziness, now i had sleeplessness, and lower back pain whenever i masturbate. But when ever i googled "side affects of masturbation" or something similar i found everyone encouraging me "its good,healthy" and stuff. So why does all these people lie? They can't b true i've experienced all the ill affects of masturbation. Finally i have stopped masturbating and hope i'll improve with my mental and physical health. S0 what i exactly want to ask is why does everybody say its good? And can i reverse everything i it was just by not masturbating(also good food and exercis)? Thanks guys and keep it up!:)
