Thanks, I can compose a better response now.
Hiv is a virus which attacks the immune system (as i'm sure you realise), and part of the immune system is the network of lymph nodes. You will find these on the side of the neck, in the abdomen and groin, armpits. They attempt to harbour any infection, and when they do, they swell. Salivary glands, and indeed any other glands, are not related to the immune system and do not swell as a result of infection.
I strongly doubt that a few gins of a weekend will cause any medical problem unless consumption is excessive.
Your unprotected episode ten years ago is of little worry, but there are certain things you must consider:
1. Each episode of unprotected sex with a person who is hiv positive carries roughly a 1 to 3% risk of infection (it's a difficult virus to transmit). Since you only had one encounter, the odds are very much in your favour, and even more so if you don't know for certain that they are positive (statistically speaking, it is more likely that they are negative).
2. It is common for people who are hiv and do not recieve treatment to have aids related symptoms at 8 to ten years after primary infection. The fact that you haven't should be of some comfort. However, strictly speaking, you had unprotected sex with someone of unknown status and medically speaking, that warrants testing.
Whilst I would suggest that it is highly unlikely that you are hiv , a test would certainly alleviate your fears. I am confident of a negative result.
Best wishes.
