My girlfriend and i were having sex last night and everything was awesome. After i got off, i went down on her. It smelled a little funky but i just ignored that and kept going. After i took her home and went to bed, I was getting horrible heartburn in the middle of the night. When i woke up and took her into work this morning, she said that she went to the doctor and "Has a horrible yeast infection and cant have sex for a week." Could i have gotten her yeast infection in my mouth, and how can i cure it?????
