I'm not sure about the working out part since I don't but should :) but it's not really good to have intercourse with a yeast infection, for the reason you can pass it back and forth between the two of you. Now what you and your bf did should be ok and I don't think it will affect your recovery as there was no penetration. Good luck to you!
I was told not to work out when I had one. I think because yeast thrives in damp warm places. plus your immune system dips a little bit after your work out.
I was also told not to use tampons while I was recovering. I had one once that lasted three weeks! It turns out that the stuff u buy at the store only kills 3 kinds of yeast. There are like 10 different kinds. So if you still aren't feeling well in a week, I'd see a doc.
ANewlife is right. You can pass it on to ur BF, if he's not using a condom.
I hope you feel better soon.
