Wouldn't like to have those ants in my pants.
Here's a link to an Aussie stinger ant. Recently it's venom has been found to kill cancer cells.
Romsey Australia: Lethal Ants
I used one or two bulldog stinger ants in some kinky fun way back. Tied up, placed on body under a glass, anticipation etc,etc. Anyway, they place their stinger in and walk around in circles to get better depth to release the venom. Stings like hell, creats a welt, but unless you are allergic, in the end like many other insect bites it's pretty harmless.
A far as the kinky stuff, no ants, were harmed
yeah, I know, Im a sick fucker.
