But a number of circumcised men revealed they resented their parents and wished they were left uncircumcised

It is a hot-button topic that has been the subject of much debate for many years, but now, a group of men are sharing their frank thoughts and feelings about circumcision – and how it feels to have had, or not had, the procedure done.

The men took to anonymous confessions app, Whisper, to reveal their deepest secrets and anxieties about the procedure, which typically occurs at birth or early infancy in American culture, with some circumcised men admitting they ‘resented’ their parents for making the choice for them, while those who have not had it done admitting that they feel ‘left out’ because of it.

'I'm uncircumcised and I don't like it,' one guy revealed on the app, which allows users to anonymously share secrets and connect with other unidentified users.
