Anal and particularly prostate stimulation is considered taboo, but in reality it is a widespread practice that exponentially increases the pleasure of orgasm. If the stimulation is also vibrating, one can touch heights of pleasure never reached before.
A category of Sex Toys exists for this purpose: anal vibrators.
The anal vibrator is a unisex sex toy; one cannot claim to know pleasure in all its forms without ever having tried one.
Made or lined with non-porous material, the anal vibrator turns out to be an easy-to-clean sex toy; this results in better hygiene and longer life of your special sex toy.
