Yeah, I shipped Tomoyo/Sakura from like... fourth grade on, honestly. I support Syaoran/Sakura as well, but Tomoyo and Sakura's relationship is just so sweet!
I realized I like girls two years after getting into this anime, so a lot of it does have to do with being able to relate a bit. Honestly, I wonder if they made me more comfortable with my orientation as a kid.
