This is one of the best silicon toys I have purchased. (I have a few).
The primary purpose of this cone is for stretching myself for being fisted, and for being able to insert my silicon fist. Also to make use of some XL butt plugs.
So far there have been no negative aspects of this piece of silicon.
It is slightly textured on the outer surface, which helps hold onto your choice of lube.
I have been using a thicker water based gel, but find a hybrid lube is as good.
Using this in the shower makes perfect sense, as it is easy to clean up everything when you are finished.
It certainly is heavy, which helps it from moving away from you during playtime.
Easily recommend this to anyone wanting to stretch, and control the amount that you insert.
An amazing gradual stretch, gets you really open and love the deep feeling
