First of all, let's differentiate between HSV 1 and 2.
HSV 1 is mainly oral and 67% of people under 50 have it. The majority will never have a cold sore. It's not the same as being "immunized", but we can't be reinfected.
HSV 1 can transmit via a BJ, but only if that's the primary infection. That's unlikely to be the case for any of us.
HSV 2 is mainly genital transmission, and you can still get it if you have HSV 1. HSV 2 is what you risk when you get a pussy slide.
The herpes simplex virus, or herpes, is categorized into 2 types: Symptoms of herpes include painful blisters or ulcers at the site of infection.
