I shaved my pubic hair at the base of my penis and most of the skin has become a crusty rash. This is now happening on my penis. I’ve never had sexual intercourse, so I’m not sure what the problem is!

Itchy after shaving: Why it happens and how to stop it
I've shaved my pubic area... Now what do I expect? Is there a major risk of ingrown hairs or itches?

Shave an area only as much as you need to remove the hair.
However, extra care must be taken not to get any of this powder onto the very sensitive areas of the vagina or penis.
