I feel like a true internet perv voting
Kissing? Why stop there?, but I don't think the game or Link should be limited. If the script guys want a romance, then Nintendo shouldn't be ashamed of making it happen.
As long as the romance has a purpose for the story, I am all for it. As for actually showing kissing or more advanced kamasutra sessions on-screen.. well, I suppose kissing is FINE - kids gotta learn someday and Zelda is great for learning..
Nintendo is good at implying things through dialogue or through the characters' emotions so there's no need to
show anything beyond basic animated kissing.
