Welcome to the forum.
HIV is rarely transmitted by oral sex. One analysis by CDC estimated the risk of penile to oral transmission, if the penile partner has HIV, at once for every 10,000 exposures -- which is equivalent to giving B-Js to infected men once daily for 27 years before you would expect to be infected. And even that may be an overestimate. And these data are only for known-infected partners. People rarely lie about HIV status when asked directly, so it is unlikely your partner had HIV. But even if he did, for the reasons above you really were not at significant risk. However, in the future, I suggest you have the HIV status discussion before having sex, and avoiding it with partners who are positive, haven't been tested recently, or seem evasive about it.
The risk of herpes, i.e. transmission of an oral HSV-1 infection to the genitals by oral sex, is higher than for HIV, but still occurs rarely -- as a guess, probably no more than once for every 1,000 such events, IF the oral partner has oral herpes. And there's probably a 50:50 chance you aren't even susceptible -- if you are among the half the population who have had HSV-1 and therefore are immune to a new infection.
All things considered, the risk is low enough that you do not need testing for any infection. Of course if you get blisters or sores of the penis in the next couple of weeks, get it checked out. Otherwise, you shouldn't worry at all about this event.

Cuts in the mouth, sore gums, etc are extremely common, so there must have been billions of oral exposures in their presence -- but still very rare HIV transmission. This does not significantly increase your risk. Don't worry about it.
Hello Doctor, Thanks very much for your response. However, I was mainly worried because I did have cuts inside my own mouth. I performed oral sex on a man while I had bleeding gums (a few drops of blood).
Would that increase my risk of contracting the HIV virus?
