She can show him back to back episodes of Buffy the Vampire Slayer....... it has action, pretty women, romance and sex....!!! He'll understand SOME aspect of it at some stage!!! However if it were me, I'd show him something like Men in Black or Evolution, or even Lara Croft Tombraider! It wouldn't do too much for romance, but he'd get a kick out of the action and Lara Croft and her impossible pair!!!
And all you need to do Skydiver is picture yourself and the person YOU have the hots for, decide what it is you would want to happen and then change the names to the subjects.
The Cronoses tell me that actions speak louder than words any day!
