This is a true story
I wasn't circumcised at birth and grew up with a brother that was and lived in a community where 99 percent of the boys and men were.
I began masturbating at about 11 but didn't ejaculate until about 13. I had some group masturbation sessions with friends from 12 on.
I always liked the look of a circumcised penis and the tight skin on the shaft.
At 13 I asked my parents to have me circumcised, which they did. The surgery wasn't bad and after about two weeks all was healed.
I have to state that masturbation was much more sensual after the surgery. The tight skin on the shaft transmitted more feeling as the skin didn't slide up and down. The area below the glans and the scar tissue were extremely sensitive and gave more feeling. The cut area below the glans seemed to consist of the nerve endings of the nerves that previously ran up the foreskin making for the new, very pleasant sensations.
Having no foreskin I had no more odour and didn't have the smegma to clean off under the foreskin.
Masturbation was much more enjoyable and later in life I always enjoyed sex and all the woman I have had sex with preferred the cut penis, especially during oral sex.
My wife and I had our son circumcised and he too has never regreted it.
This will cause much negative feedback, I assume, but I have had both types of penises and prefer the cut one.
