Q&A: Why do uncircumcised men have little bumbs on the underside of their shaft?

Question by Sarah: Why do uncircumcised men have little bumbs on the underside of their shaft?
I’m curious about uncircumcised men… I tend to notice men who aren’t cut have little bumbs on the underside of their shaft and sometimes around the head of the penis. Is it genital warts or hair follicles or and STI? I have no idea.

Could be hair follicles, could be an STD. Google pics and compare.
