I had sex with my partner a couple of weeks ago and a day or two later he complained of itchy
red pimple like bumps on his groin area and testicles
. He said this had happened before with a different girl he'd had sex with, and it was caused by my bacteria interacting badly with his own causing folliculitis. He started taking a topical antibiotic and applying that once every 8 hours. The bumps started to go away but keep showing up in different places (face, armpits, side, arms).
