From left to right, by diameter: 1.6'' metal plug, 1.75'' lovense Hush 2 M, 2'' glass plug, 2.25'' lovense Hush 2 L.
I very very recently (~Feb 20) just got the lovense Hush 2 Large and it's soooo big. I managed to work it in me only once so far after over an hour of warming up and trying.
I can fit the other 3 plugs in me, but the glass plug takes some warmup first with a smaller plug. I need lube to get any of them in, even the smallest metal plug, and with toothpaste...
