@FindingLibido Closest thing is probubly the njoy plug of the same shape, which i keep eyeing up in the sale at the moment.
@LWels95 hi, sadly prostate toys arent something i know alot about. but there should be some recommendations in the forum if you dig through the threads. This one is the best place to start, there is alot of good info in there 
@LuciousLegs oh gosh, i really dont know. Theyr designed to be used during sex though so you might have trouble keeping them on with a semi or less. Theyr more designed as a toy to make your penis feel wider i think.
Most of the out and about toy options if you have a penis are p-spot or butt plugs (i think you might possibly be able to use some of the cock rings for it too, but youd have to check.) but there is a set of vibrating undies on the website too
