This sign is bullshit, I accidentally put my prostate massager in my butt all the time, sometimes twice in one day.
I know from first hand experience you can't do it by accident as one time, hung over and showering in the dark in the early morning i got a little dizzy and sat down.
Perfectly meeting my starfish to the shampoo bottle on the floor. It could not have been more on target had i attempted this.
I shot up, seeing stars like for real for only the second time in my life. I wasnt dizzy, I was up and at em' baby. Wooo what a rush! Hurt a lot for a minute. Hard as i sat down I don't think that bottle tip made it a millimeter into my pooper.
So yeah, impossible
The sphincter is one of the few muscles that is contracted by default, and you have to consciously loose. So yeah, unless you have some medical condition, not very likely to get something in by accident
contracted by default
Cool, what others are there? Also, goofy question: what's the relative strength of this 'outer anus'? It wasn't listed in my search for strongest muscles and most results are tips on gaining anus strength
Its different right after anal sex, when your muscles are still relaxed.
... that sign ... they just kept it because it seemed funny after they retrieved it from a pacient.
