The external section is quick rigid, and the inner sleeve is weirdly stiff. There's silicone points inside - meant for pleasure - but makes it quite painful to use.
Would not recommend.
I've warned my partner for years one day I would buy him a new vagina, and well I finally pulled through, he had a bit of a laugh, but then we gave it a go, he says it feels weird but good thankfully he still prefers the real thing. But we will use in future as a foreplay thing, and who knows if he will try it while alone.
