I am experiencing regret and worry about a recent encounter. I met a man on the internet and we masturbated each other and he put his finger in my anus for a while, not hard or very long. He did not have an orgasm. There was no oral or anal sex. I have been married for 20 years and have not had any other sexual partners. My curiosity has finally gotten me in a bad situation. I read your site and understand that this is probably safer sex, but can you address the following exposure risks. 1. HEpatits B. 2. Herpies. 3. HPV. 4. Syphilis. 5. Anything else I might be at risk for. I am not having any symptoms, but feel itchy and super aware of my body, examining it frequently. I am worried about putting my wife at risk. Thank You
