CDC has a whole thing on it

Circumcised men compared with uncircumcised men have also been shown in clinical trials to be less likely to acquire new infections with syphilis (by 42%), genital ulcer disease (by 48%), genital herpes (by 28% to 45%), and high-risk strains of human papillomavirus associated with cancer (by 24% to 47% percent)

By all means, you should still wrap that shit. But if you're living in a rural community or one that has a strong stigma against contraception, or you're just in a place where the disease is rampant and you need a secondary precautionary policy, this will have a meaningful impact on disease spread.
