Transmission through open sore in mouth

[looking4love]

I was at a bar and I was open-mouth kissing another guy who later told me that he was HIV-positive.  He was very aggressive and kept biting my tongue and lips really hard.  I also bit his tongue and lips a little as well, but nowhere near the intensity that he was biting mine.  I went home later and I noticed that the inside of my lip was bruised and it looked like the skin was torn.  A week prior to this, I also had bitten my tongue and my tongue had not fully healed by the time I was kissing this guy. 

I understand that saliva carries minimal amounts of the virus and has proteins and enzymes that can kill the virus.  My concern is whether I was able to contract the HIV virus through the wound on my tongue or through the opening on my lip caused by his biting.  What if he had a tiny amount of blood in his mouth as well, possibly from me biting him or from him having bleeding gums, and it entered the wound on my tongue or the opening on my lips? 

I am worried and I would like to know if I should consider taking any PEP medications?  This incident happened less than 40 hours ago.  Thank you in advance for your time and respectful answers.

At no time were you ever at risk of contracting HIV from kissing. Saliva does not transmit HIV and contains over a dozen different enzymes and proteins that inhibits HIV transmission.

Rod is correct you didn't have a risk and PEP is not warranted for a no risk encounter .

HIV is acquired via unprotected vaginal or anal sex , from mother to child during childbirth and from sharing drug injection equipment with an HIV positive person immediately after they inject .

As long as you use condoms for vaginal and anal sex you will avoid HIV , its that simple .

Thank you for your replies.  My concern is that this guy, who is 100% HIV positive, had bleeding gums or blood from me biting his tongue/lips and we somehow  exchanged blood.  I had a sore on my tongue that hadn't healed completely and he had bruised my lips from biting them. 

Could some of his blood from him having bleeding gums or blood from me biting his tongue/lips have entered my blood stream when he bit my lips and bruised them?  Or could it have entered my blood stream while he was biting my tongue which already had a wound that wasn't fully healed and could have easily started to bleed? 

I also noticed that I have lost 2-3 lbs already even though it's only been less than 72 hours since we were together.  Could that be due to my metabolism or immune system revving up to ward off the HIV virus? 

Thanks again for your time and respectful answers.

When we are giving risk assessments we always assume the partner is HIV positive with a high viral load. And in your case the assessment is that you were not at any risk firchiv in the scenario you described.
