We'd hate tell anyone how to live there lives, but this top needs to think about some endurance training. After lying on his back and getting blown and a few minutes of vigourous love making, he's ready to pass out.
Sure, this scene is hot (look at how hard he gives it to that bottom while he's dishing it out) but man this guy needs to learn to run marathons, not enjoy some great, messy sprints. We'll be watching either way.
