Hi, my partner and I have been having issue with sex. Basically his dick hurt and would be red and get a rash after we have sex sometimes. The rash turns to dry skin. It started first in October and has happened a couple times since then. We don’t have stds/stis. I noticed I had gotten a yeast infection at one point and that was the worse time for him. Is it possible my prescribed antibiotics aren’t working on my yeast infection and I just have it off and on? I don’t appear to have symptoms but I have noticed a slight itching sensation every now and then. We do have anal sex so maybe we aren’t using enough lube? The lube we use is water based. We are just confused and want to get back to having sex comfortably lmao. Any help or feedback is appreciated.
