Lip numb and pain after licking guy at a sex club

[Stephenpd6969]

I know this may sound strange

. I want to a gay sex club 2 days ago. I engaged in mutual touch and inservice oral (I got blow jobs). At one point there was a guy going poppers. I touched his penis with my hand and licked his neck. Next, the strange part. Minutes later my mouth felt a bit numb
30 min later I had a small painful white spot on my inner lip.

I am trying not to worry about HIV. Any thoughts on the mouth numbness and pain? Could he have gotten some of the poppers on his neck, then I gotten that in my mouth?

If there had been semen on him, I assume that it would have been exposed to air for a bit (I did not notice semen)

Thanks for your help

You had no risk for HIV so a test would be a waste of time. There are only 3 ways HIV can be transmitted and you didn't do any of them.

HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.  
Only 3 adult risks are the following:
1. unprotected penetrating vaginal with a penis
2. unprotected penetrating anal sex with a penis
3. sharing needles that you inject with. Knowing these 3 are all you need to know to protect yourself against HIV. The situation you describe is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. Doctors have calculated the risk from what you did to be less than that of being hit by a meteor. The above HIV science is 40 years old and very well established.
I have no idea why your lip went numb so you would have to ask your doc.
