Real: Most likely with his princess in one of his returning trips. It will be adorable and sweet. Syaoron: With Yuuy, anytime now. It will be rushed as fuck because they're both building up on ridiculous levels of UST. Fay: With some guardian back in Celes-land, it was kind awkward and then Ashura eventually killed him. Yay. Mokona: Lol no. Sakura: Lol no. EVENTUALLY she will marry her Syaoran and have the sweetest vainilla-est sex ever. Clow: Uhhh I like to believe it happened with some mentor/teacher of his that he charmed into an inappropriate relationship because it just fits him, idk. Doumeki: If I'm not remembering the times wrong, depending on the definition, either with Hima or Wata. It was awesome either way. Sei: To his mommy like the good Seishirou he is. It was creepy as hell. Ueda: I can see him waiting till marriage, so. uhm. He had sex with a robot. Yay? \o/ I'm sure it was lovely. Riku: God, I need more canon.
