I've known quite a few men who have been circumcised as adults. Three of them did so because their doctors told them they had to because of Phimosis and constant infections. The rest all did it for religious purposes, and I knew two were seriously considering it for esthetic reasons because they "wanted to look like most other guys". To the latter, I told them to seriously consider the fact that if they later regretted it, there was no restoration (at least at the time)! For those that went through with it for whatever reason, not one ever voiced regret, though all admitted it did take some getting used to because the sensation was "different".
Every time I think about this I'm so grateful to my parents for having had it done to me. And while I certainly do appreciate foreskin on some men, I'm glad I don't have one and don't envy them a bit. Kind of like tattoos I guess. I don't have any and glad I never got any, but I can appreciate them on other men. It's all a matter of taste, if you'll excuse the pun. 😜
