Involuntary Measurement

No idea how it would be possible to measure.

Hey @WallyBanger ,

Has anyone measured the distance an aneros travels during honest un-assisted involuntaries?

Not as far as I know - only with visual judgment. Precise measuring is quite difficult.

Does it vary from model to model?

That seems likely. But IMHO, more important is the type/strenght of the involuntaries (involuntaries vs Auto-Fucking).

I'm about to try measuring and hope to compare results. By use of camera and by feel of finger, I'm know it's not nearly as much as the sensations would suggest.

Iit's not so much indeed. What do you hope to gain from the results?

No idea how it would be possible to measure.

Maybe with equidistant markings on the aneros (like they use with crashtests)? There are still two types of movements to consider: sliding (where the clenching of the anus forces the aneros to slide and dragging (where the whole anus moves and drags the aneros with it).

Looks like it is possible with more accuracy. Search xtube for anerosometer. Be sure to start with the "prep" video, then open two windows and play the ass and meter versions together. Be sure to get them synchronized carefully....
