You would have to have some kind of disability to not understand that the person having unprotected sex with you today had unprotected sex with 20 other people just in the week prior to seeing you... And that's just compounded the more they work and the longer they've been in the industry.
These people are just asking for a disease and then they're shocked when they finally get one and they have to tell their wife to get rid of it
This happens A LOT more than you think and I've known the idiots that do this.
The one girl f*cked people raw for a year and had no symptoms and had no idea when she got the disease. She potentially infected hundreds of people if not thousands and men were furious with HER for getting a disease when THEY pressured her for bare services. It was suddenly HER fault that THEY had to tell their wife.
