Now my age is 23.I have been masturbating for the past 6 years... Initially I use to masturbate for 5- 6 times a day, then slowly reduced the frequency...Now I am masturbating 2/3 times a week. The problem is I am not getting the erection like before... When I kept my legs together, i am getting good erection, if I seperate my legs and in some positions, erection is very poor... My penis is also slides towards the left... I dont have any problem with ejaculation, but after ejaculation my penis pains for 6-7 hrs and then returns back to normalcy...Suddenly, my cheeks started to sunk little bit and also some of my hairs gone white...I am really worried... Please help me...
