Mam/sir I have habit of prone masturbation to seeing porn video from three years. I controlled myself from eight days and not do prone masturbation. But yesterday I do this I feel very guilty how I controlled this. Is hand masturbation is good or bad. I suffer from erectile dysfunction and my penis is very small and thin and it looks curve when erect it down in 2 second how I cure myself I feel depressed I am able to sex in future or any problems come my hands and legs are shivering sometimes I do only one time in one day as people do with gf or wife so why problem came from prone masturbation and not doing sex.
