In the last 25 years I contracted syphilis twice - both times in the span of about 6 weeks a few years ago.
Got it from getting blown by a crazy broad I picked up near a mental hospital.
I remember sitting in the back seat of my car with my pants down and this crazy broad ranting something about how she doesn't usually do this on a first date. I knew she was nuts but she was kinda pretty and she didn't ask for much.
Plus, a hard cock has no conscience.
Got the Penicillin shot in the buttocks and had a follow up a couple months later and told the infection was cured.
Also got/get tested for HIV regularly, negative.
Also had the cotton tip thing shoved up my prick once. I wanted to strangle the old broad performing the test.
