Thanks for your query.
Is usually done as a part of religious ritual or as a part of some medical complaint related to genital organ.
It is usually performed for phimosis
, a condition wherein one cannot retract ones prepusal skin while urinating or during sexual intercourse.
one survey regarding carcinoma penis states the incidence of cancer being less in muslims and the reason for low incidence in them being circumcision.
The chance of smegma
accumulating between the glans penis
and prepuce is nil post circumcision and the cause for the cancer being smegma.
It does not mean that one should go for prophylactic circumcision,but genital cleanliness by cleaning genital organ daily while taking bath by retracting prepuce fully and cleanig is mandatory.
So you do not need to think of this proceedure since it is not bothering you in any way.
Hope I have answered your query.
I will be available for your followup queries if any.
