Sir I have been suffering from nightfall since last four years. I told my parents about that but they said that it's natural at this age (I am 22). But I think the frequency at which it occur isn't natural. Sometimes it happen continue for four five days.my concentration is also very poor and I think this is due to same reason. And at the same time how much I resist but i couldn't help watching hot pics of actresses and my eyes goes to their private parts.when I try to control and does not see that constantly it came in my mind and become unable to concentrate on my work and study. Sometimes I look at women inappropriately , I feel very bad and obnoxious abt me that how can I do such filthy things. I don't want me to watch such things. I want my mind always watch good things but I could not help. After watching such stuffs I feel very guilt and filthy. Please help me sir.I am very good and intelligent student but this thing is making my life miserable.i want to regain myconcentration.
