About 4 days ago, my husband noticed 2 small pimple-like bumps on the very top of his buttcrack, right near his tailbone. 2 days went by and they turned into one large, very irritated sore. On the 3rd day, 4 similar-looking bumps appreared on his penis shaft, and 2 on his scrotum. The original bumps on his backside have begun to scab over, but are still about the size of the last knuckle on my finger. And today, we woke up to find he has a tightly grouped cluster of bumps now on the underside of his penis shaft, this time closer to the head. The original bumps on his penis now seem to be forming the same way the ones on his butt are, into one large irritated mass. What is going on?
