I asked a friend of mine who is a nurse, she said:
You should ask your doctor but .....consistent use of condoms lessens the risk of further exposure to HPV and protects the cervix from further irritation.
In some mild cases of dysplasia it can clear on its own, over a period of time - others need intervention.
Be careful not to irritate it further - maybe condoms are the best way to go?
Good Luck x
