I have no scientific data whatsoever :tongue: but I was thinking about a large top that was uncut versus cut. Seems to me the extra skin on the uncut dick would thrust in and out with more of a "treadmill" effect. A cut dick would be more likely to chafe and pillage as it was thrusting in and out. Of course, patience and lube would help either situation but any thoughts on this? I'm thinking about anal sex in particular. On a related note, any preferences when btm'ing for cut or uncut? I've never done bb the few times I've btm'd. This might be a moot point with a condom.
