I would call it nothing more than an innocent joke, he pressed the matter for a second and then just let it drop, if someone is too delicate to hear that kind of langauge maybe they should have considered joining a monastry or something, he just lightened up an otherwise boring press conference with an off colour joke (and got alot of free advertising in the process)

To clarify i don't think someone should be talked to in this way all the time but if people should be able to handle the odd sexual joke, i think the setting was important as well, he was just trying to get a point across in an entertaining way and thats why he pressed the issue with the translator...
