Actually very sorry - my bad - you mean why would a married gay man insist on partnering someone of the same sexual orientation when, if they had been partnered with Kai/Graz/Gio - the ''curse'' speculation wouldn't happen and their husband would not have to go through that.
I don't think John asked for Jojo. No source for it at all. He may have asked for a same-sex partner and when interviewed, had narrowed it down to Kai, Graz, Jojo and Aljaz based on height alone.
The producers will have decided the pairings based on chemistry, height, headlines, single or married status (showmance), who the sleb/agent ''asked for'' etc etc
I liked that it was Johannes because I wanted the validation for Johannes - he loved that on Strictly he could be himself and I thought well, actually, why use Graz when Jojo is just as tall? But there was always then going to be the ooh chemistry-curse bollocks going with that - that happens to many couples who are het every single year. Equal opps sleb twaddle in action - they are not being treated any differently. (although that said, am not sure I have seen anything other than 'powerful and electric' mentioned....yet
)
If Rylan's single now, I expect him to get namedropped with Craig or Jojo or John etc before the series is out, such is the nature of sleb blinds and sleb tattle. yes, I am just as guilty of gossiping
