Hi there ~
I understand your concerns for your boyfriend. I believe that you have no problems except the itching that is concerning your boyfriend. The itching may be relieved with anti itch medications like chlorpheniramine
maleate available as Avil
in many countries, over the counter. I also believe that you may do well to wait till the lesions heal while using symptomatic treatment. Keeping the area clean and dry will also help your situation. I hope this helps.
Take care and have a lovely day!
