Sorry, nope. The same thing could be said about ANY choking scene ever put in a movie - the difference between that and erotic asphyxiation (the reason David Carradine died) is that the choking is inflicted as a means to kill.

Leia wanted to kill Jabba. The end.

Although I never quite got how... was Jabba's neck at his back??

Well.... There's a bit of a sexual element between Leia and Jabba. Jabba wants Leia, makes her wear that bikini, licks her face... Leia is revolted. That's about as far as it gets, but it is sexual.

As for choking Jabba, she's putting the chain around where his neck would be, were he a human, and pulling. That, I suppose, is how you strangle someone, more or less. She's on his back because she has to stand behind him, but he's huge.
