I recently came back from a skiing holiday in which i received oral sex with a condom on. However 2 days later i started having itching on my testicles and today (3days later) a red rash has appeared on my testicles/scrotum, there are no other sign on my penis or elsewhere. A condom was used throughout but I am still concerned this could be herpres. The only other thing i can think is that its a fungal infection from wearing latex leggings throughout the week skiing for many hours as the only current signs are a red rash and heat from the scrotum/testicles. Thanks.
