Apart from the oldest question in mankind: "Does penis size matter?", I've studied a bit this other debated issue - what's better for a woman, circumcised or uncircumcised? Let's get stressed out by this other question, not that men aren't concerned enough about their masculinity.
It all depends on each woman's point of view in the end and they seem to go fifty-fifty on this one, unlike the other case where most of them say SIZE DOESN"T MATTER. Social background, religion and number of past partners are also key factors to take into consideration when a woman gives you an answer to this question. The main argument for choosing circumcised men is that sex is a lot smoother with a circumcised partner and that circumcised men tend to have less problems keeping a condom on. Other (rather silly) answers would be it looks more attractive and it feels better during oral sex. Actually, it seems women prefer circumcised partner for oral sex.
As far as climax is concerned, a particular survey shows that 83% of circumcised men's partners achieved orgasm, while only 53% of uncircumcised men's female partners achieved climax. One interviewed woman stated that she enjoys a circumcised penis because of the "different taste, smell and better looks" of those penises and added that "bathing results last for longer periods of time".
Clean that pecker
Cleanliness is another key-issue that most women take into consideration and, like our interviewed female friend above, they prefer circumcised because it's cleaner. The tendency would be in favor of circumcision, but surveys results are rather close and conclude with each part in favor for an equal number of times. The results conclusions are also 50% of the time in favor of one kind of penis, and 50% in favor of the other.
Let me conclude this one in favor of the circumcised penis because the overall impression that I got is that women usually prefer the bald eagle instead of the soft turtle neck.
