I have burning sensation during urination and defecation problems. Is this due to the unprotected sex?

Hello doctor,

I had unprotected sex with one girl at the end of the previous year (she is known to me). Then, three months ago, I had protective sex with another girl with a protective condom. But oral sex was done without a condom. Then I knew the previous girl has HSV 2 (herpes simplex virus), then got upset and started post-exposure prophylaxis for HIV (human immunodeficiency virus) the next day, and 24 days have finished. Then last month, my legs started feeling tingling and burning and burning of urination. Also, I had defecation problems. I consulted a sexually transmitted doctor, and all tests were done, including HIV at 3 months, all negative except HSV 1. I have had it for the past 10 years. But the doctor asked to get Acyclovir 400 mg, and I took it for 18 days because still, symptoms have not improved as other doctor told me I have prostatitis. But while on acyclovir, the penile lesion appeared and vanished after seven days. A week before, I only did an antibody test for HIV, and it is negative. Please identify and help me with this.
