Penis characteristics

[B_slimjimpencil]

do you notice any differences between distinct penis characteristics and the duration of sex?

for eg.
cut vs. uncut
long vs.short
thin vs. thick
rock hard vs. floppy

i ask because i am uncut and i know because of our foreskin we experience more sensitivity so i was thinking that cut guys in general may last longer. so i am curious to see if this among other differences correlate to differences in duration of sex

I think long, short, thick,and thin are all preferences but I'm pretty sure nobody wants a floppy one...lol
