herpes would not be high on a diagnostic list based on what you have described. while it would be impossible to blindly offer you a definitive answer without examining you more likely possibilities would include chaffing (like you mentioned) or a fungal skin infection (tinea cruris also known as jock itch) -- a common skin condition that occurs in warm dark moist skin areas. you would need to see a medical provider if this condition persists or worsens. this is really the only way to be properly diagnosed and treated.
i have a small rash on both inner thighs only where my testicles touch. what could this be? . i noticed the rash while showering a few minutes ago. the rash is very small and only where my testicles touch my thighs. i also feel very small bumps on the irritated area. no rash on penis or testicles. could this just be chafing? it has been hot out and i usually don't skip showers but i didn't shower yesterday if that makes a difference. could it be herpes?
