Uncut adds more mystery to the cock and makes it look bigger eye candy. It tends to slip inside my pussy easier because of the way the foreskin moves along the shaft when pushed back by vagina tightness.
Cut and uncut both turn me on if I know they are wanting to fuck me urgently. Some pre-cum leakage adds to my excitement, which I can lick before I submit my bottom for a good shafting.
cut and uncut both have advantages... really depends on the person taking the dick as to what they like... uncut dicks tend to be less "abrasive" when fucking because the foreskin moves along the shaft so there is less friction (but in a good way)... cut on the other hand, you feel every inch, lots of rubbing... if you're not the extremely wet type, or if doing anal and unexperienced, uncut is better... cut on the other hand will tear you the fuck up, which for some of us, is a GOOD thing
