Any particular reason why Fleshlight?
Those wanting a Fleshlight only likely to ever place a single order.
Go with someone like
Lovehoney, where they can buy a Fleshlight, then be repatriated customers for all sorts of masturbators and sex toys for the Mrs too, plus lingerie. Unless you're specifically posting Fleshlight content, therefore attracting that specific audience, then you'll be better with general sex store, offering a range of products including Fleshlight.
