Is it normal my uncle is an adult film actor, and i watch his movies?

My dad's younger brother is a porn actor and he does straight porn. He's about 34, good-looking guy and in really great shape. Everyone in our family all know about the kind of work he does and we're pretty much fine with it, but we never really talk about it.
The thing is, I secretly watch my uncle's movies. I even googled his screen name before and found out that he's done over 120 porn films. It's not because I'm into him (that would be weird) but more of because it's a side of my uncle that I don't know much about. We hangout sometimes, and he seems so chill and normal, and totally not the guy who does hardcore films. My friends sometimes show me videos of his movies and they go "Man, that's your uncle? He's so lucky!"
Every time we have a family reunion or whatever and he's there, I can't help but look at him and think about what I've seen him do in porn! I've seen him run around, play, and cuddle with my other nieces and nephews who are about 4 to 10 years old, and he seems like your typical cool uncle. Whenever he's laughing with the rest of the family, having a beer with my dad, or talking to me about how I'm doing in school, all I can think about in my head is, 'You're my uncle and I've seen videos of you banging five girls and shooting all over their faces!' (sorry if it's a bit graphic).
Is this weird?
I'm his nephew, by the way..
