Circumcised or Not: Can Men Tell a Difference?
One study, published in the journal "Sexual Medicine," found that circumcised men were more likely to be able to tell the difference between a circumcised and uncircumcised penis than uncircumcised men. However, the study also found that there was a significant amount of variation among men in both groups, with some men being able to tell the difference and others not.
Another study, published in the journal "The Journal of Sexual Medicine," found that men who were circumcised as adults were more likely to be able to tell the difference between a circumcised and uncircumcised penis than men who were circumcised as infants. This suggests that the ability to tell the difference may be learned over time and experience.
Ultimately, whether or not a man can tell a difference between a circumcised and uncircumcised penis is a matter of personal experience and preference.
