90% of women I know prefer the look of a circumcised penis and are OK with sucking it because its cleaner. Its like a man has freed his cockhead for action and uncut can be cheesy and smelly and look just awful. Circumcised men are a turn on. Uncircumcised are not.
Circumcision is the norm in America - most doctors recommend the procedure for baby boys, and so the likelihood of coming across a penis that is not circumcised is low, and therefore a little uncomfortable for women who haven't seen one before. Of course, if you've only had one sexual partner, then whatever you've got is what you have, so to speak, and one is no more attractive than the other.
Women prefer circumcised penises. For one thing, a circumcised appendage is easier to keep clean and, therefore, creates a more inviting sexual situation. Plus, the extra flap of skin on an uncircumcised penis is a turn off to most women who perform felatio. Females prefer the sleek look and feel of a circumcised erect penis.
I love my cut dick - it's so high they say it's a Kentucky cut - 'cut back to the balls'. And it looks awesome. What's not to like? Girls like it, boys like it. Circumcised just looks better and who wants a cheesy dick? Foreskins are disgusting! Circumcised is cool!
It is impossible to definitively state whether a circumcised penis is more attractive than an uncircumcised one. What people find appealing in members of the opposite sex is large due to societal conditioning. In cultures in which circumcision is customary, women are pre-conditioned to find circumcised penises more attractive. Likewise, in cultures in which circumcision is not customary, the opposite would be true.
While American women are used to circumcised penises and the initial sight of an uncircumcised penis is a bit shocking, they are equally as attractive. In Europe, the opposite could be said with the same result. It's about perception and the person who is attached to the appendage that makes an experience.
