Infant hand foot and mouth on groin?

Summer • 11/6/18👦🏻 11/28/19👶🏻 March 2021🤰🏻

Can hand foot and mouth spread to groin area? Our pediatrician said today my poor baby boy is starting hand foot and mouth, she didn’t give us much info other than watch his temp and switch off Tylenol and ibuprofen, but now I noticed the rash looks like it has spread to his penis area, can this happen?
