Hello, I am a 25 year old bisexual male. Last month, I tested negative for HIV. I have participated in low risk behavior and no intercourse for 8 months. I struggle with depression and it's been rough lately. I recently had unprotected anal sex (Top) 4 days ago. It was a stupid decision and I was not aware of the persons status. I had anal sex again today (bottom) and it was the first time since 12/2016. It was extremely intense and aggressive, and immediately after, I felt moderate pain in my groin. The pain only occurs when I touch specific spots in my groin, not when pressure is not applied. Is moderate to severe groin pain a symptom of an early HIV exposure, or could this be from having agressive anal sex (bottoming)?
