Wear a condom like I do, I've never cought a cold never mind a gash scratch, show me a w.g. That don't do bareback if only with her boyfriend. Don't let paranoia spoil a good hobby, this pass time is full of taboos and dark matter and things most people would shate them selves at what we're up to and doing on a regular basis, I wear a condom for all anal and vaginal sex but I do love owo , it's a calculated risk, yes, but it's great and if I should catch a scratch, well that's my bad and off to the gum clinic I will go.
