What causes red mark on lips after performing fellatio?
For the last three years after performing fellatio on my husband I get something that looked like a read mark or a hickey on my top lip at the bow. It usually lasts 24 hours. I never had this problem until the last three years. I am now 46 my guess was that the bloodvessels are weakened with age but I'm really guessing? Hope you can shed some light on the cause.
