I was recently circumcised for medical reasons, and although i find it easier to clean, i've found that it's caused some desensitization(sp?) and i've found it's made it more awkward when it comes to self pleasuring, as i pute the foreskin to use.
I'd never experienced intercourse before i had it done, but my gf might comment later about her opinions on the aesthetics of pre/post-circumcision
