Australian doctors are reporting a rare case of penile shaft skin cellulitis complicated by a ruptured abscess in a healthy young man, caused by non-penetrative sex with his partner. 

The case is significant for doctors, as the infective pathogen was Streptococcus intermedius, an under-recognised cause of suppurative infections, the Victorian urologists say. 

The 34-year-old soldier presented to ED at the Northern Hospital in Melbourne complaining of intermittent penile swelling and pain following sexual activities. 

“The swelling first occurred after non-penetrative sex, that is, ‘dry humping’ his female partner three weeks [prior],” the doctors wrote in BMJ Case Reports.
