Is it safe for an adult man to get circumcised?

Infant circumcision is one thing -- it is almost always safe, rapidly-healing and non-traumatic (particularly if anesthetic is used). Adult circumcision is a more involved matter -- healing is much slower and can be complicated by erections. Adult circumcision typically requires abstinence from masturbation or intercourse for between 4 and 6 weeks. Still, circumcision protects against some diseases-- and I believe that adult circumcision may be medically warranted in populations at very high risk for the diseases (i.e. human immunodeficiency virus [HIV]) it is known to protect for. It is also advisable in cases of painful or dysfunctional phimosis (inability of the foreskin to retract from the head of the penis) or other, rarer, problems related to the foreskin.
