text: does a man must be circumcise? what happen if a man not to be circumcise? does he will have any problems when doing sex, if he never been circumsise? i was not circumcised until i was 50.  you have great sense in the head of the penis when you are not circumcised.  you have great feeling inthe head that way when having sex.  once circumcised it feels diffrent and i dont find it any better.  i miss my foreskin.  you dont have to worry about sex or anything   just keep it clean and enjoy it.  many women get turned on by it and some dont like it.  your doctor will check the foreskin to make sure it goes back but that is no problem.  unless you have a medicla reason do not get it done.  keep that foreskin,  i miss mine
