Sure, I'll try to help! All of the contestants are bisexual so anyone could theoretically end up with anyone, which is supposed to be the appeal of this season, but seems to be throwing most viewers for a loop. Kai is the only self identified transgender person in the cast (female to male). Paige is just a skinny, androgynous cisgender (the term for "not transgender") girl.
As a bisexual woman with a growing preference for women, I can see how it would be possible to think that some of the participants are actually gay, especially with the men because we equate any effeminate tendencies in men with homosexuality and in general society is skeptical that men can even be bisexual, and that bisexual men only identify as such as a stepping stone to being gay.
On that note, I felt bad for Basit - it's obvious that Jonathan has a lot of issues with internalized homophobia and especially disgust with femininity in men, As he went on and on about how he only likes femininity in women and could NEVERRRR be attracted to a feminine masculine person. Only BIG BEEFY BRAWNY BEEFCAKES for him! Which is ironic because Basit is actually very fit and muscular, but Jonathan can't deal with Basit wearing skirts and eyeshadow. Basit was right to call out Jonathan for basically suggesting that he should be with Danny because they're both effeminate. At the same time, Basit picking Jonathan at the match ceremony was stupid. Dealing with dating biases sucks, but you can't guilt trip or lecture or bully someone into being attracted to you, and you should respect yourself enough to know that you deserve better than constantly trying to convince someone to see you that way.
