Eh, might as well continue in the “day of not bothering to censor stuff” trend. It’s not as if Google is ever going to let me run ads here, so why play by anyone else’s rules?
What you’re seeing in this picture is actually an argon gas scrotal inflation (normally in gaseous inflations CO2 or O2 is used, or sometimes just air, but that feels terrible when your body absorbs it for most people). Inflations like this are fascinating to watch (or do) because they’re just so fast in comparison to saline inflation — start to finish times are measured in seconds and minutes rather than hours.
PS. There are a few videos of genital gas inflations on BMEvideo.
