Inflatables safe inflation size

So, my questions is, is there a safe maximum inflation diameter for inflatables, anal or vaginal?

We have usually go by the if I can't push it out it's big enough. A bit more if I leak too much. I do not do vaginal inflation.

I think it depends of how much I can stretch my ass….a bit of pain, is ok, but if the play became painful, something is not right……

For me 2 inches, till now, of wide is enough

Be safe

What does it matter? You can't see it when it's inflated inside you, anyhow.

If it hurts, STOP!

Ok, so I found a site where they have measurements. According to rectum physiology the widest part of the rectum is about 2.5 in.

So after that your stretching the walls Now I don’t know how much elasticity there is but that’s what you would be dealing with.

After a good clean out I pumped the inflatable up. At about two inches I could feel a pleasant internal pleasure. At 2.5 inches that sensation increased and I felt it on my prostrate. I went to 3 in. and it became a strong urge to expel. Of course there was nothing to expel, it was the expandable causing that reaction. I relaxed my sphincter but of course the inflatable was too large to expel, though it did open me. Still was a very heady sensation. I think my ass was confused, LOL

I like the your in trouble now thing with the balloons inflated tight in your bottom…..

I agree 2” is pretty wide

Since you cannot measure it while inside, I assume you measured it outside, after some number of pumps, and then applied that number when inside. Since most inflatables will become roughly spherical, your rectum is not that shape. Inside, the inflatable will likely take a more cylindrical shape, and the max diameter will be less than you see outside. Maybe you can measure the volume of air by inflating a spherical balloon with that pump, and measuring that…

So, yes I did measure number of pumps and related diameters. The material is heavy and I tried to squeeze the inflated sphere but it took a great deal of pressure to change the shape.
