Circumcised men are less likely to get and pass on HIV to their female partners.

Male Circumcision (Updated January 2009))
Male Circumcision Trial Findings:
* Three randomized controlled clinical trials in sub-Saharan Africa demonstrated a 50-60% reduction in risk of female-to-male HIV transmission among men randomized to receive circumcision compared to uncircumcised controls. This evidence is supported by long-standing ecologic and observational data.1
* Elective surgical male circumcision confers a partially protective effect against HIV acquisition for HIV-negative men at risk of acquiring HIV from HIV-infected female sexual partners, and may be particularly effective in populations where HIV prevalence is high and male circumcision prevalence is low.
I'm very happy with my snipped member.
