Are more gay men circumcised

No, most gay men in the world are not circumcised. Consider the fact that most circumcisions are done before the child reaches adulthood (and in fact, most are babies). How would the parents know what the sexual orientation of their son is?

Also, most of the world does not practice circumcision, and gay men make of 3-8% of all men in every society, so most gay men live in places where there is no circumcision.
