Yes reduce masturbation as much as possible. to control sexual urge, do abdominal breathing. Do it for 10 minures twice a day. Instead of using will power, use this breathing to cam your urge. you can do male deer exercise,kegel exercise, prostate massage specially anal peripheral prostate massage. It a pleasure tool as well as treatment.If you can learn kundalini yoga, it will help you to build your sexual stamina. keep patience. Google all the above exercises. they are good.
Hi:
There is a possibility that you might regain the ability to get and keep an erection if you try going a couple of days between masturbating. There is no guarantee, but at least it is a place to start.
