The cleaning thing is a myth btw. Dicks, just like vaginas, don't need to be washed with anything more than some running water and very gentle abrasion (unless they've gotten some large amount of dirt or foreign objects in them). They likewise both have a microbiome, which is modified significantly by circumcision.

I know the link to lower STIs is often brough up as well, but it's got shaky evidence. A recent and very large Danish study found that over "more than three decades of observation, non-therapeutic circumcision in infancy or childhood did not appear to provide protection against HIV or other STIs in males up to the age of 36 years. Rather, non-therapeutic circumcision was associated with higher STI rates overall, particularly for anogenital warts and syphilis."
