Cool. It's the perfect date for me to run across this question.
I never "got into" or "turned on by" poker. Can't even say I decided to play poker. It's just part of who I am and how I was raised. Poker is basically the common language in my family and has been a source of income during hard times in my family for generations.
Gramps always told me that part of becoming a man was being able to hold my own at a table against him because when I could do that, I could support my family no matter how hard times got.
Don't know how old I was when I started playing, but I know I hadn't started pre-school yet because my grandmother was quite vocal on that particular point.
Most of my good family memories involve poker in some way now that I think about it, and the same seems to hold true for my mother. (She's a very dangerous live-game player by any measure)
So I didn't start playing poker out of any intellectual interest in the game itself, not out of greed or necessity, or even because once in a while it gives me enough of an adrenaline reaction to feel alive for a moment. Those are just a few of the bonuses I discovered along the way that keep me coming back.
