On day 1 I had unprotected sex with an ex-girlfriend three times. Then on day 3 I had protected sex with a high risk prostitute. Then on day 5 I had unprotected sex with ex-girlfriend again. On day 8 I went to the doctor and he examined my genitals and found nothing suspicious. Tested me for Chlamydia, Gonorrhea and Herpes PCR from swapping tip of the penis. All which turn out negative. However, ex-girlfriend had a "yeast infection" on day 8. She said she had red irritated skin. She said she has had a yeast infection before and everything looked typical of that type of infection. She took Diflucan from a prescription the doctor gave her before and her infection disappeared completely after 5-6 days. I was just looking to get a professional opinion of these events.
