I hate to link to such crap television, but it's as good an example as any.

He's 31; he's in his prime. She's a reasonably attractive woman, but I think he's panicking at the thought of never being able to enjoy other women in their prime. I think he's desperately hanging onto his youth through obsessive bodybuilding for this reason, and I don't blame him. I feel bad for him. She seems half dead already, and he doesn't even come across as a bad guy. Even his flirting was tame, and it's obvious he's very lonely and disconnected from what he wants.
