How To Attract and Seduce a Pisces Man When NOT In a Relationship?

So, Pisces men. They're so confusing, and yet so attractive! I have my eye on one I know, but I mainly want to see how far I can go in terms of a sexual relationship. We flirt all the time, but mainly with our gestures toward each other. How can I make him more interested in flirting and more willing to join in the flirting? What is some body-language that attract Pisces men? What are some things to say and do to him or even near him (haha) that "turn him on?" Please and thank you!!
