Suspected yeast infection?

Patient: For the past year I have had redness and soreness on the head of my penis, and also all around the underside of the head, where the head and the shaft meet. The redness and soreness is made worse with sex, especially if the sex is when my girlfriend is on her period. There are also bumps that have been forming around the underside of the tip (I believe called penile papules, from my internet research) and I am not sure if these are related to my other symptoms or not, but chronologically it seems that they are, as they began appearing shortly after the other symptoms (redness & soreness).

Symptoms: Redness, soreness, bumps
