I had unprotected sex almost a month ago. The tip of my penis, just inside the urethra has been tingling since less than 12 hours afterwards. I initially thought it was an STD, but urine has shown nothing, I have no discharge, no pain urinating, and no external symptoms, and I took antibiotics and an antiparasitic just incase. I felt ill for about 3 weeks, some of that was undoubtedly stress, but the tingle in my penis head, as well as muscle aching, shooting down legs, and abdomen pain were not all made up. I now realize the antibiotics could have helped a yeast infection grow stronger, I think. I have wondered about herpes, but I never got any lesions (I did take some valtrex though). I then stumbled upon yeast infection information. I have had a yeast infection on my shaft before, but it is not there now. I noticed my lips felt rough on one part about a week ago. They still do, and when I pulled the lip tight and looked closely, there are white specks under the skin. My question is, if I acquired a yeast infection through my penis, does it make sense that it would be manifesting itself in my mouth? Also, I had been in a pool all day. I was dehydrated and sweaty and slept in damp shorts, are these things that could make me more vulnerable to a yeast infection? Do symptoms start that quickly?
