Was my own cousin checking me out?

Let me describe the way he looked at me and let you judge what it was. I was sitting on the edge of the pool and he was in the pool and he stopped and just looked me up and down. It was really weird and I made a face at him. And then he looked me in the eyes for a few seconds then he just swam away. It was disturbing because he is my cousin who I grew up with, were the exact same age and stuff so its not like he is a creepy old molester uncle I thought he seemed pretty cool. He was always a bit of a playboy but not to me Im his cousin. but maybe I was being paranoid. maybe it meant nothing. What do you all think?
