sex after yeast infection

I had a yeast infection diagnosised 5 weeks ago after having it for roughly 3-4 weeks.  After the first 2 weeks of treatment it seemed to still be there so I had a second round.  For the past 2 weeks I haven't noticed symptoms at all except maybe that I was still sensitive. 

Last night I had unprotected sex with my SO and I was kinda raw after.  Happened another two times and I was wanting to make sure that's normal after an infection?  And when do you go back to normal?
