I don't remember seeing one. It's always a background shot, or back of the guys head. There has never been lipwork on display. They really should show one of the main characters - preferably Toby - getting a ball draining blow.
Well from what I heard there are a set of reservations about doing a more vivid example of sexual acts. One many of the male actors are actually straight so things like that might cause a little problem as far as comfort level. Secondly it was discussed about have a few more gay actors to play rolls where it could be shown, but since Here! isn't a porn channel they are not going to go that far, unless they begin to charge for the shows episode specifically. That would be on top of the $7.95 that some of us have to pay on our cable networks.
Gael Garcia Bernel has actually performed it in "Bad education" but later it was altered in many version.But i think many of Europe version they have retained it
