The Doc Johnson Decadence Thumper is not at all what it claims to be. It claims to work for G-spot stimulation as well as external clitoral stimulation but I don’t have a clue how they came up with that idea. It’s only 4.5″ long, an inch of which is the battery cap. There isn’t a drastic enough curve for G-spotting, and it’s so slim that if it reached your G-spot lengthwise I imagine it’d be a royal pain to position the wimpy little tip where it needed to be. I honestly cannot see it working for even the shallowest of G-spots.
I mean, it’s supposed to be waterproof so maybe they want you to just stick the whole thing up in there. Even then you’d have to do a lot of clenching and if you’re lucky you might maybe POSSIBLY get some level of stimulation.
If you could get over how weak and buzzy it is.
