HIV, kiss and irritated gums

[Avatar1987]

I'm on a 6 month course of Isotretinoin (Accutane) to treat severe acne. The only side effects that I have are gum irritation and bleeding gums and  minor cracked glans penis. Here is my question:
I had a casual encounter with another man of unknown HIV status. There were only kissing, mutual masturbation and oral sex (I was the recipient). My gums were not bleeding at the moment we were kissing, but an hour later, when I got home and flossed my teeth, they bled. Could I have been exposed to HIV if my partner was HIV+? The kissing thing hasn't lasted long, since I was aware my gums were irritated. I tried to keep my mouth closed as much as possible. So, not much of oral exploration, just brief introductions of my partner's tongue inside my mouth, but not "passionate open-mouthed" kisses. He also performed oral sex on me briefly and my glans had a small scratch, but not bleeding. Any reason to be concerned? Is PEP recommended?

You don't have an HIV concern, you never had an exposure.

Hi Tek, sorry for the silly question, but that means that I don't have to refrain myself from kissing, even if my gums are irritated and bleed when I floss them?

Not if your concern is HIV. HIV isn't transmitted by kissing, bleeding gums or not.
