This is our least favourite category of sex toys for many reasons. Mostly, we think using a list of 'best selling sex toys' to figure out what sex toy you want is a terrible way to buy a sex toy. Sometimes sex toys are 'best sellers' because the company spends a lot of cash on ads, or because a product has become a near monopoly in a particular category, or because a worker owner woke up on a particularly good side of the bed happened to write an atypically great review of a product causing us to struggle to keep the "Best American Erotica 1997" in stock for a full decade.
Having said all of that, sometimes sex toys sell well because they're just that awesome, and heck, 1997 was also a great year for erotica! So, obviously, feel free to use this list however you'd like, but always remember that a well marketed sex toy is different than an amazing sex toy, and just because something sells well, that doesn't mean that you're going to love it.
