In less than 24 hrs of unprotected sex i notice 3 boils or hives in my public area.one went away, one dried up, one had white pus. what is it?

Boil: Boils are referred to as abscesses, in the medical community. They can occur from breaks in the skin, which provide a route of infection for bacteria to form an abscess (collection of pus/infection). When this happens, you may need to see a medical provider who may need to prescribe you antibiotics or incise and drain the abscess. Some home remedies may include a warm compress and ibuprofen.
