First let's get one thing straight: you can't have sex with an actual octopus or octopuslike monster—octopuses are animals and therefore cannot give consent. But octopuslike monsters totally exist in tentacle porn, which you can absolutely watch and get off on. It's hot, not only because it's so foreign and forbidden but, according to some experts, because it fulfills some pretty classic other fantasy tropes, like bondage and multiple penetration. And if your ideal penis is actually a giant blue tentacle, the sex toy manufacturer Bad Dragon just may help you fulfill your monster fantasies.
