You should keep using the cream for a couple of weeks past when the symptoms disappear.

My doctor gave me a cream about two months ago and helped but i came back and the cream i have now i have been using more 3 days and it has helped a little i think but hasnt cleared it up completely yet. I didnt start having the problems right after i received the oral sex. I started having the problems after i got really sick from some kind of food poisoning this summer about 2 or 3 months ago.
How long have you been using the cream?
If it is fungal, yes, you could spread it to someone, and yes, you could get yeast from oral if someone has yeast orally.
The only over the counter treatments are creams. You might ask your doctor about diflucan, which is a prescription pill for yeast.
