In my experience, lots of cut guys like uncut cocks, and lots of uncut guys like cut cocks. I think there's something appealing about another guy's cock being "different" from one's own. If that's the case, you might find yourself liking uncut cocks after you are circumcised.
One thing to consider is that once you are circumcised, the result might or might not be to your liking, and there's no "undo" button like we have on the computer. I won't offer an opinion one way or the other about getting it done, other than to suggest that you be very sure of your decision if you do it,
Perhaps it would help to experience lots of other guys' cocks, both cut and uncut. That might give you data to aid in making your decision…and if not, it would be a lot of fun ;D
