I've been seriously considering getting cut, precisely because the foreskin makes chastity more difficult for me. I wonder/worry about losing sensitivity however. There'd be pros and cons to this for me if this fact were true. On the one hand, the fact that I am in chastity doesn't mean that I don't enjoy sexual sensation (I just can't do anything about it), and on the other hand I think the foreskin makes the belt less secure as it provides stimulation (lots of nerve endings in foreskin) even when the penis is supposed to be in a steel tube.
Thankfully my foreskin is not too tight because it had to be rolled back when using cage type devices or devices secured by my PA. In full belts with a tube I find that the foreskin can suffer from oedema when fluid gets stuck in there due to the bend in the tube. This usually resolves itself and isn't painful, quite the opposite in fact.
A foreskin complicates hygiene no end, folds of skin inaccessible to fingers or sometimes even soapy water are not good.
In summary: Foreskin=nerve endings!! Nerve-endings=fun!!! Circumcision = loss of those nerve endings!!
However, practically, and in terms of chastity, yeah cut works best. So, I'd say for games: No but consider a PA, for serious long term chastity, where chastity is part of your identity, then yeah.
