I got circumcised about 2 years ago. First, I’ll say that there’s a difference between sensation and pleasure which people often confuse. I’m definitely less sensitive and have to be tougher than I used to be, but I still find sex and masturbation just as pleasurable. Orgasms feel the same too. That said, sex feels pretty much the same for me, and my wife says she can’t really tell the difference as well. Masturbating is the most different because the mechanics changed. Personally I preferred the feeling of my foreskin because it gave a broader sensation, whereas now I really only get sensations from the head. That and lube gets annoying if I just want to beta one off real quick.
