hi i'm 21 ,i was sexually abused when i was 12 ,since then i came to know abt masturbation.i used to masturbate while watching explicit images & videos but the problem is that this habit still persists ,i sometimes control & hold myself for abt 2,3 & rarely 4 months but after that my desires kind of take a toll over me & i completely loose control & masturbate(this period sometimes persists for 2,3,4 days or a week),this thought creeps me as sometimes i'm able to control my self & feel strong regarding my senses & on the other i feel helpless,i dont know how to control myself ,can u suggest me some technique so that could self treat myself ,without undergoing any treatment. ?
