Playing Zelda OoT, questions

I've started playing Zelda OoT, and I was wondering. I'm right after you say farewell to Saria and head for Hyrule Fields. So, do you get to have sexual intercouse with her in the end? What about Zelda, Malon, and Ruto, especially the last?

The "E" for "Everyone" doesn't mean you get to have sex with "Everyone" in the game.

Or ANYONE for that matter.

Why is there no "M" rated Zelda game?
