I think my first big famous person crush was Ralph Macchio (The Karate Kid). I was 5 when it came out, lol.
All my constants are much older... Harrison Ford, Sean Connery (after he hit his 50s and went grey), Mark Harmon (also the "older version"), Toby Keith. A newer one the last few years is Jason Momoa (Game of Thrones, and some movies-- he looks like he'd be fun to hang out with, and not bad to look at at all!)
In real life, I'm drawn to tall, dark, more on the husky side, blue-collar type.
