I have this movie scene in my head but can't remember what it is! A guy is jerking off and he climaxes just as someone walks in on him. I remember the guy screaming, "I can't stop, I can't stop, I'm sorry!!!" as he continues, er, finishing. A little help?

Grandmas Boy

"What happened to you last night"?

Halfway through your post I would've said 'Fast Times at Ridgemont High' but I think chsis_sc77 got it right with 'Grandma's Boy.'

Here's the scene, because I know people are curious.
