I remember getting into a text argument with a WG years ago - and her counterpoint always stuck with me...
"But I get tested regularly..."
"How regularly?"
"About every 3 months."
"Well, when was your last test?"
"A few weeks ago, why?"
"And you've been barebacking clients in the meantime, I assume? You see my point? Getting tested every blue moon, isn't a form of protection."
"Fuck you."
No thanks.
