I'll wade in....
'Safer sex' has never been on my radar except with men. Oh and that brief period in the late '90s when I was into leather sex with women and it was too dark in sex/BDSM clubs to really notice open herpes sores, especially with my glasses removed and a blindfold on.
I did get tested every six months though. For everything.
I've got a spare dental dam if anyone wants it...powder blue. Unused.
