Oral sex with ejaculate after dental cleaning

About 2 weeks ago I had a guy *** in my mouth. I totally forgot that I had a dental cleaning earlier in the day. There was some bleeding with my gums at the time. That was around 11:30 in the morning and the oral sex took place later that night, almost 12 hours later. Another dumb thing I did was to floss my teeth at home that night after brushing - about an hour after activity. Can anyone tell me how big the HIV risk is in my case? I've heard you're not supposed to engage in oral sex with cuts in your mouth....but how does this situation compare?

zero risk

Really? Wow...well that does make me feel a lot better. I'm just so confused about why they often warn you about having oral sex then. Seems like unless you're actually bleeding at the time then there is no risk for HIV infection through oral sex from what I understand.
Thanks for your reply Lizzie Lou
