Just a heads up, there is a NSFW medical image from a 19th century textbook about lesions caused from arsenic that includes an image of a scrotum and the shaft of a penis.
*gasp*!
Yeah, it's funny until your 60-year-old conservative boss glances at your monitor and fires you.
NSFW warnings aren't about prudery, they're about protecting people from prudery.
I appreciate the warning too but for an other reason, looking at pictures of something like lesions is very upsetting to me. I am not happy of it, but it is real.
