I needed to get cut at 24 - 7 years ago. If anything, I feel more now than I ever did. I remember being a bit worried because I had heard about a loss of sensitivity, so i was really surprised the first time I had sex after I'd healed - it was amazing. It still is!
I guess it must be a personal thing but honestly, I don't understand the "foreskins have more sensitivity" argument. I couldn't be happier.
BTW - my wife (then girlfriend) prefers me the way I am now. She also says she can feel more now.
