Is it necessary for all guys to have circumcision for hygiene purposes?

Cicumcision. No it is not necessary for all males to have cicumcision to be healthy and normal. If you have problems however, you should discuss this with your doctor to help with the problem.
No way. You don't need a circumcision if your foreskin retracts easily and you wash under the foreskin daily either in the shower, bath or basin.
