I grew up around sports. I played from the age of 5 until the age of 18, when I started watching them instead. I've been talking to a guy recently. He's smart, has average taste in music, is mature, sweet... and nerdy. He's NOT athletic. He doesn't work out (never dated a guy who doesn't make time for the gym) and while he doesn't dislike sports, he's not really into them. I definitely watch more ESPN than him, and I DON'T like that.
On the flip side, I don't know if I could handle dating a guy who was like OBSESSED with a certain team or sport.
