SILEXD Thermo-Reactive Dual Density Girthy Silicone Butt Plug 3.5 Inch

I bought this, the middle of three, having bought the small and large first. Liked the small after a couple of tries, but the large was too much of a jump, so thought this would help ease into it. It works for that.

Firstly the good, it's nicely made, feels good quality, the dual density construction makes it heavier than you might expect, which is good. The fact that you can squish it and it holds its shape for a while is neat, and the ability to soften/harden with heat cold is cool.

The bad, and this might just be me, but it's a show stopper for me. Using it to size up, I put it in once in the morning, kept it in for a while, then took a rest. Then put it back in a little later, and as I stood up, I felt it move. On checking, the flange had more or less disappeared up where it shouldn't. I panicked, but managed to get it out without too much drama, but it scared me enough to throw it in the bin. I fear the flange, being made of the same soft silicone as the rest of the outer, is just too flimsy, it squishes too easily when the toy gets pulled in through natural suction.

This may just be my experience, but be aware.
