You had no risk. Oral sex is not considered a risk by HIV experts because saliva contains proteins and enzymes which create a hostile environment for the HIV virus that renders it inactive. Furthermore, in the last 40 years since the disease has been studied, repeated studies of serodiscordant couples, in which one partner is positive and the other is negative, have shown no instances of infection where oral was the type of sexual contact being used by the couple. If in 40 years no one has ever gotten it this way with an HIV+ partner then you're not going to be the first.
There is no reason why you can't follow-up with your partner's doctor to get the necessary confirmation that you had no risk.
As an FYI, this is a volunteer site and not a 24 hour helpline. The volunteers respond when they are able to do so with their schedule. When you continually bump your thread, it appears as though there are already multiple replies to your post, which is likely why no one replied before this.
Please anyone? The 72 hour is fast approaching.
Thank you!
