There are as many sexual fantasies and preferences as there are people out there. When it comes to the male organ, it seems that the majority of women, at least in the US, prefer a circumcised penis mostly for aesthetic reasons. At the same time, a smaller minority actually like the uncut penis, primarily because they enjoy the sensation of feeling how foreskin is moving back and forth during sex. This is not something a woman who has never had sex with an uncircumcised man would know.
More importantly, however, is the fact that being circumcised or uncircumcised is rarely a deal breaker to a woman, if she otherwise likes you and is attracted to you for other more significant and more compelling reasons, such as your personality, confidence, ambition, sense of humor, etc. I am yet to hear a guy being rejected by a woman just because he is uncircumcised. So, if you are uncircumcised because of your country of origin or for any other reason, don’t concern yourself with that too much, and focus on other elements of who you are to make yourself more attractive and more desirable to the opposite sex.
You might meet a woman who would tell you that she really prefers circumcised men before you have sex. Don’t let it bother you too much, especially because she might enjoy having sex with you for a number of other reasons, and your being uncircumcised will turn into a small and relatively insignificant factor. If you are an interesting guy who also happened to be a giving, exciting sexual partner, whether you are circumcised or not is unlikely to make that much of a difference.
