I think there's a scene in 'Bad Education' where he is fucking his old lover while he's passed out. If you look at it CLOSELY (like I have) and you zoom at the bottom, I think you can see him grabbing his dick... like, maybe, if he were masturbating. It's very small (not the dick, the angle) and you have to make it out. Maybe I'm seeing things and maybe I'm not. I don't know how to put caps here so I'll let you do the investigaion on your own. If someone does find the info, please tell me if I'm right...
