Hello sir, I am 25 years old virgin male, I had never done sex, though i started masturbating at the age of 16 and do it once daily, but sometime i skip for 2-3 days or maximum for 10-12 days. My problem is that I can easily pull back foreskin of my penis behind the when it is flacid but i have to work a little to roll it back. Also when it is errect, i can pull back my foreskin till 3/4 of the way, and pulling further gives a small sensation of pain on my foreskin. I am worried about this problem.
