Penetrable sex toys for men have come a long way from synthetic vaginas—or “pocket pussies,” as they are more commonly referred to by teenage boys. Thanks to several innovative companies, today’s masturbatory sleeves are sleeker, more high-tech, and, well, less creepy. To wit: Tenga’s Original Vacuum Cup, a pop-art version of the brand’s signature “egg” and “cup” toys. When I first came across the Vacuum Cup, which promises “an amazing suction experience,” I pushed a few free samples on a couple of male friends to see if it lived up to its hype. Sure enough, one friend described the inside as “fleshy and tight,” admitting the experience “didn’t last long” because it was such a snug fit. Another gave it similarly rave reviews, despite initially scoffing at the satisfaction of penetrating an amorphous hole. The company says it doesn’t design its products to look or feel like the inside of a vagina, but these revolutionary sex toys are a lot more promising than the pathetic imitations of the real thing.
