So my partner has some spots on the shaft of his penis. One came the other day and was kind of like a yellow scab, then today he has another tiny little bump that looks like a super tiny blister.  He was complaining about being itchy. We are refraining from sex and going to wait a few days and see how it looks. Maybe it's some sort of pimple or ingrown hair. It doesn't look like the pictures on the Internet, not such a big cluster. So we are going to keep an eye on it.
