Let me explain it, physically he probably doesn't me on like an actual look by look basis, but to him there is no one more desirable someone he'd rather be with, kiss, or be with at night. More beautiful *not attractive. To me that is why the word is powerful because its more than the looks.
It's all situational. Depends on the guy and you. When you love someone you start to believe they are the most beautiful person in the world. In other circumstances they may just be trying to get in your pants. Work off your intuition.
