Have you got any pictures of the bit where they are becoming mates?? is it... The bit like this picture

If you go to the Avatar Wiki -->link <-- you'll find some there. It takes a little digging, but look under Na'vi culture and go to the page on "Mating." Hope that helps!

I don't have any on file right now but I'm sure if you do some digging in the images section, you're sure to find some.

yea i saw the extended version wen it was put back in theaters and it was weird. but they didnt do it like normal humans. they didnt "push it in". the just hooked their ponytails 2gether and started kissing. it was beautiful. but i dont hav any pics though sorry
