Rapports d'cul ?
Rapport anal sounds very clinical.Nop.
"Rapport anal" would do I guess, refering at all the (sexual) thing you can do with an ass and everything else.

I guess you got a point.Well we would go on perhaps inapropriate debate but "Rapport anal" refers to any sort of sex with the butt, so it should fit "buttsex".
"sodomie" is just one of many "rapport anal" possible, like "anulingus" wich is an other possible "rapport anal" ...
So if "buttsex" is general, that would fit, IMO.
