I love Tezuka, but I also find him to be the single most frustrating TeniPuri character (possibly even anime character in general), precisely because he's so bad at admitting what he wants/needs (to himself and to others). As much as I want to, I have a really hard time shipping Tezuka successfully with anyone as a result. Hopefully he's starting to get at least a little better at that (and maybe in the process will stop putting Sanada up on quite so much of a pedestal, because Sanada definitely has his flaws too).
