I am a married male. I am now almost 60. I was born in the USA. In school, there were only two uncut cocks. One was an Asian guy born in Asia. The other, my best friend, was born at home to a poor Italian family. His older brothers and father were not circumcised, so he escaped the knife. When we were young, 12-13, we learned to masturbate at about the same time. We did it together sometimes. I saw he needed no lubrication, and the head of his cock was slick and smooth all the time. He also seemed to have such huge sexual pleasure from his foreskin, and would get hard by rolling it in his fingers. He also often had an odor that would stimulate me tremendously, though I never told him. Later in life, in my late 30's, I wished often for a foreskin. I was in the medical field, and as plastic surgery advanced, I noted that skin was stretchable, and would remain that way. I began by attaching weights to my (very tight) foreskin with tape, and allow the weights to hang down my pants leg. Usually not at work, as the weights would sometimes tear off and drop out of my pants. Home and weekends I kept at it. The skin stretched very fast at first, and in a few months I could cover the glans and lightly tape it closed with paper tape. One morning, there was some red stuff in my new foreskin, like crumpled crepe paper, I later realized it was the old dry skin of my glans. My cock was so sensitive after this shedding that I was constantly half hard and oozing pre-cum, making big wet spots on my pants. I was in constant sexual excitement and needed sex more than once a day. We have the gift of an unplanned son due to my new foreskin. I kept at the extension, some with tape, rarely with weights, and it grew slowly so now it is always covered. It won't stay covered hard, but I can pull it up and can't imagine jacking off without it. My sexual pleasure is at least doubled, and after the initial reaction my wife had of thinking I had gone cock mad or something, she admits that the seal of cock and vagina with my cock slipping in my skin and her greater stimulation has resulted in more and harder orgasms for her.
I wish everyone could have done this, or avoided circumcision. Guys who are not cut don't know what they have, and cut guys don't know what they are missing.
