Circumsicion has no impact on the proportion of the penis. All penises smell/taste bad when hygene is neglected. Unciricumcised penises don't touch and retract the sensitive areas of a girl, makes it sound like a tentacle, made me laugh. If I grow old and die never again hearing that someone's 13 year old daughter has a preference for uncircumcised men my life will be so much better.
Uncircumcised penises do provide less friction than circumcised ones, but typically only during withdrawl when the foreskin slides back. It doesn't have real impact on the pleasure a woman experiences during sex. Some women like circumcised pensies, some do not, most have no preference whatsoever.
