I love Michael. There's a video on Youtube titled Summer Kyle 911 where his character, Kyle, starts to do a striptease for his girlfriend, Summer. If you brighten the video (your monitor brightness probably won't cut it, suggest downloading clip and brightening with editing software), he has a hard on that's pretty noticeable, mostly when he lays back on the bed after they kiss and after he's taken his shirt off. I don't want the internet police to ban me because of copyright infringement so I'm not posting the direct link, but this link will get you most of the way.
