I'll say it again pussy slide is probably more dangerous than BBFS for the guy.

The problem is the worst viruses and viruses in general pass really easily through blood.

If your inside a nice warm wet soft pussy. Even if her juice has got HIV/herpes etc.. it's gotta get through your dick skin to infect you.

When you pussy slide, if she shaves her pussy. The stubs are creating microtears all around your dick... And then the slide is rubbing her juices directly into the cuts.

The only thing worse than it is anal bbfs (receiving) and sharing a needle.
