Our friends at Movieline noticed that the sex scene between Jake and Neytiri that was axed from the movie is in the script Fox posted online. The Na'vi don't have sex like humans—they have "the ultimate intimacy."
No, these giant blue creatures don't need genitals (so then why the loincloths?) because they have their pony tail-like "queues" to mesh together. Riding your woman is just like riding a banshee, except the wind isn't in your face. Check out the dirtiest bits from page 90 of the script below. It's almost enough to...uh, make your hair stand on end.
