Am I the only one thinking Catra blushed seeing new She-ra transformation, because it included Catra's mask? XD
I also think that as far as Catra would probably prefer to be top, it wouldn't be out of her character to want to be topped by Adora.
And I guess curiosity would leave them to try She-ra stuff in bed eventually, but i still deeply believe Catra would rather prefer for Adora to stay Adora.
I guarantee you, without the slightest sliver of hesitation in my heart, that there is nary a lesbian in the entire world who would not at least -entertain- the idea of having sex with their girlfriend in her 8 foot tall amazon goddess form.
The shift from the old She-ra form to the new one represents Adora slowly learning to allow herself to have emotional attachments to other people: what allows her to access the new form in the first place is her concern for Catra. The new version also only shows up once Adora and Catra are on the same side. It makes sense thematically for Catra to have some level of dislike for the old She-ra form, but not for the new form, imo.
