your symptoms sound classic for jock itch but definitely follow up on it with your provider since you were recently in the ocean. Recently being on antibiotics also puts you at higher risk for fungal infections as well as staying in wet bathing suits in the heat too.

Nah haven't seen the doc seen him before I went to fla bout prostatitis prostate was swollen took antibiotics and when j got home from the beach it's red was itchy some bumps on the bottom side of my testicle
This encounter was 4 years ago and the rash only now surfaced? It sounds kinda fungal like jock itch. Have you seen a physician? Maybe try some Nystatin. That has always helped me for rashes in between scrotum and thighs. Lots of sweatiness in that area and chaffing. It wouldn't appear to be herpetic based on your observations but you can always get a swab after you tried the ointments. Never hurts...well...except in the urethra, but we won't talk about that.
Also it hurts some when I push in on the area testicles have been sore but been cleared of gonorrhea and clymidia
