Chill Dude..from your history it all appears fine & you dont seem to have much to worry about!!
As you say, no exchange of body fluids, no real sexual penetration & no admixture of blood & blood products....so you seem to be realtively safe clinically & to begin with, i dont think any testing was required.
Having said that, your test shy of a few days, does not matter..these things are not absolute!
You seem all fine but at the next available opportunity , repeat the test whenever time permits more to give yourself closure than anything else. The mind is a funny space & that can play on you whatever anyone tells you !
However do remember that it is better to be safe than sorry & whatever your sexual leanings be or whatever sexual act that you practice, remember do always practice SAFE SEx!
Cheers & wish you peace & a good sexual appetite & continued good health!
