pornstar, seems like you contracted some sort of UTI(Urinary Tract Infection) , STDs(Sexually Transmitted Diseases)...
but if you are not feeling well overall and your doctor couldn't figure out what's wrong..don't worry, in community/world of spiritual folks , we're going through some level of upheavel right now. Perfectly normal people are not feeling well as well. Many are not aware , but some are getting symptoms.

Oftentimes, sex with stranger is disastrous to your spiritual self than your physical self. Having sex with people, if they happen to have auras with negativity and dark, you embrace it through the unseen vortex you create during sex, and it manifest into weird physical discomfort and unease. It's the same vortex, few partners who managed to keep their relation for years, share their spiritual energies through, rendering them to look/behave alike. You have to have feelings and compatible energy to experience these life's greatest moments. You just can't go and have sex with anyone, just coz you can but if you do, well, unconsciously, your spiritual self gets shocks and symptoms appear through your physical self.

In your case, I'm sure it's some sort of STDs, UTIs. but if not, the words are not far being told to you 'it's in your head'. You need to relax.
