you sounded like me when I was 18yo and found out that all of my friends also jerk off
when I was 15-18, I was jerking off "secretly" in bathroom, I thought I was the only one in this world who has discovered this, the only one who pleasured himself in shower room, I was somewhat shameful and thought of myself as a little horny bastard. So I kept it as a secret to myself and never told anyone. Then in first year in college in my group of male friends, I found out that all of those fuckers also jerked off, I felt relief and asked them if they also jerked off, they fucking laughed and said of course they all jerked off.
About time you open up yourself bro
