I did my comfencision when I was 10 and it was such a painful experience. I don"t think I"ve had an erection before my comfencision because my foreskin was too tight.
Funnily enough I haven"t ejaculated for a week. I don"t think this has ever happened and I started masturbating when I was 6. TBH I didn"t know what I was doing until my teens. LOL
