Actually, an intact penis is pretty easy to keep clean. Only the outside of a baby’s penis needs to be cleaned; the foreskin should never be forcibly retracted. Overzealous cleaning probably causes a lot of infections. Females have more folds and crevices than intact males and no one suggests surgery to keep them clean. here’s what the American Academy of Pediatrics has to say:

Foreskin Hygiene: The foreskin is easy to care for. The infant should be bathed or sponged frequently, and all parts should be washed including the genitals. The uncircumcised penis is easy to keep clean. No special care is required! No attempt should be made to forcibly retract the foreskin. No manipulation is necessary. There is no need for special cleansing with Q-tips, irrigation, or antiseptics; soap and water externally will suffice.Foreskin Retraction: As noted, the foreskin and glans develop as one tissue. Separation will evolve over time. It should not be forced. When will separation occur? Each child is different. Separation may occur before birth; this is rare. It may take a few days, weeks, months, or even years. This is normal. Although many foreskins will retract by age 5, there is no need for concern even after a longer period. [1984 version only: No harm will come in leaving the foreskin alone.] Some boys do not attain full retractability of the foreskin until adolescence
