Okay im a 21 year old female,
It does depend on the girl but honestly it SHOULD be what the male prefers! I mean you do have to clean an un-circumcised penis more regularly and thoroughly as it sweats under the foreskin. But it is also a lot more sexually pleasurable for a male to have an un-circumcised penis! As the tip of the penis is always covered, when the skin is pulled back during sexual or oral pleasure, it is a lot more sensitive and has a lot more feeling compared to an un-circumcised penis. Therefore is very sexually pleasurable for the male.
My partner is not circumcised, and I really dont care. Our sex life is amazing and thats all the should matter! I honestly prefer un-circumcised as during foreplay it is more comfortable for me as the skin glides back and forth over the penis so I can get a better rhythm, guys without foreskins are a bit more complicated when it comes to foreplay.
So pretty much it depends, are you putting on a fashion show or are you aiming at having pleasurable sex?
Hope I could help :)
