It's a lot more fun to blow a guy with a foreskin than one without. With cut guys, deepthroating seems to be much more desired whereas with with intact ones, the head and the frenulum is where it's at.
Any kind of insertive sex is better with a foreskin than without, much less friction. Friction is the death of good sex, especially when you're on the larger side.
Scars really turn me off too. The rough texture and the contrast in color is really ugly.
You can j/o without lube, your glans doesn't get abraded by clothing, etc, etc, etc.
Forced circumcision is pretty sick, IMO.
