Dennis is someone who really knows how to have a good time. Nolan falls into that same category. Sean Cody had a hunch that they would get along. They are similarly playful in their attitude, and they are both hung, hot and have proven they are good at fucking. They were very touchy and flirty with each other in the car. Since they were going to be spending some time out in the sun (and both are pretty pale) the application of sunscreen was necessary.
Richard just keeps getting hotter and hotter!
When he and Nolan got together, there were muscles everywhere, but there was no sense of “I am bigger than you are”. There was actually a mutual admiration for each other. It’s kind of like when it’s okay for a guy to check you out at the gym if he is “admiring” the way you are working out. Fantasizing would be more like it. And hotter.
