I have periodontal disease. My boyfriend has a severe case of jock itch. Can my disease be infecting him? Is periodontal disease contagious by giving him oral sex?

Your disease CAN infect him but I don't think it would cause jock itch.

Hahaha that is hilarious! No... generally only herpes simplex and candida (yeast infection) are common things that can cross from genitals to mouth
