echinacea and lysine don't really do anything for herpes for. if you want to have less ob's in general, you'd want to take daily suppressive therapy with one of the 3 herpes antivirals. you guys are spending money needlessly :(
in your situation, it's not likely that your partner will contract hsv2 orally from performing oral on you . as was already said, you both have significant protection from contracting herpes on other body parts in general. we never recommend performing oral when you have active lesions though - there is active virus being shed so why take the chance as well as active lesions are open portals into the body for germs and what are normal germs in the oral area, aren't always so normal in the genital area so it's actually a general infection risk for the partner with the open lesions.

Herpes type 2 does not change to type 1. And since you are both outside of the first year range of being diagnosed, your risk of it moving to the mouth are pretty much zero.
You both have the same type in the same area so you're not going to catch it in your mouth. I've given oral sex to my partner while he was having an active outbreak and had no issues. I'm not worried about it. You're fine. :-)
