Judging by the questions, and responses, on Y!A on this topic, I'd say it's the circumcised guys who are more self conscious. If you think about it, they are the unnatural ones, and on a world wide basis, they are the minority, only about 15% of guys are circumcised. I see that circumcised guys from the USA seem to think that they are a majority, but that's only in their small part of the world, and the rates are dropping. In 2009, the USA rates were down to around 33%. With insurance companies refusing to pay for cosmetic surgery, and parents being able to discover the truth about circumcision, the rates are set to drop even more. I can't think of any situation where a guy with a normal body would feel insecure, but I do know that a lot of circumcised guys are fully aware that they not complete, and try to make up excuses for their inadequacies.
