I feel the same way - it's just not fun for me. I like playing poker with my friends, but I like the social aspect of it - putting down $20 on the table is no different than buying a few beers at a bar, and I don't care if I come out of the game with more or less money.

Going to a casino, which I've done a few times, is just wildly disinteresting.

But I know I'm prone to other sorts of addictions, so I guess gambling is somehow different.
