About 2.5 months ago I had unprotected sex with a high risk woman. Although I had no symptoms, I received treatment for possible gonorrhea, chlamydia and trich (250mg IM ceftriaxone, 1gm oral azythromicin, and 1gm oral tinidazole and a week's worth of doxy). I was also test a few weeks later for HIV/Syphillis, with negative results.
About 3 weeks after treatment, I masturbated using lotion, which I've done several times before with the same type of lotion. Shortly after orgasm, and as my penis became flacid, the foreskin on my circumcised penis and shaft became swollen/puffy and red. Later in the day my scrotum, foreskin and shaft were no longer swollen but red with an irritated feeling.
When I visited the doctor a week later for the HIV test, I explained the situation to him and he gave me some steroid cream to apply for a week. The steroid cream seemed to help a bit but not much, and I stopped using it after feeling like it was also starting to irritate my penis.
The redness goes away, but comes back immediately after sex, so I haven't been very active. Even then, the foreskin and glans are enlarged (kind of swollen/puffy) and look not so much cracked but strange like kind of rinkled.
I don't have easy access to healthcare where I live, which is why I'm seeking advice here. What is this likely and how should I treat it?
Thanks in advance!
