Could oral sex cause canker sores?
A doctor has provided 1 answer
Depends: A true canker sore is an auto-immune condition that is not contagious. It can occur as a result of different types of stress. However, a herpetic ulcer can be mistaken to be a canker sore. Herpetic ulcers are contagious and can be transmitted by oral sex.
