Little Anni (I'm little Anni) learned all about his body from Jar Jar, and once he grew up they continued their relationship even as Anakin become a Jedi and Jar Jar went into politics. One thing never changed though, and that was their intense lovemaking sessions, as often as rhey could get away with. Jar Jar was usually the bottom, he loved Anakin and knew the boy was mostly heterosexual, but very open minded, so Jar Jar did everything he could to please Anakin as a woman of his species would.
