A few days ago, I made an appointment with a netizen. When she gave me unprotected oral sex, her teeth seemed to have scratched my coronal sulcus and frenulum. It was very tingling and it felt scratched, and then she took her vagina again. Sliding back and forth unprotected on my genitals, a lot of vaginal fluid remained on my coronal sulcus. I would like to ask if my coronal sulcus was scraped out of the wound or the mucous membrane was broken, is there any risk of infection if I come into contact with her vaginal secretions.
