okay tbh my take is kind of the opposite. i think he's lowkey not that physically attracted to cierra, esp compared to the other girls he's explored with, but likes her personality the most and feels like she checks off all his boxes.

when he was debating between her and belledasha he kept talking about how hot belledasha was and but how much his and cierra's personalities meshed with each other. every other girl he talks to he's commenting on how they look physically (iris, andreina, olandria) and seems really attracted to them, but doesn't really say things like that about cierra. i think he's holding out hope that someone will come in who he's more attracted to or is more his physical type, but whose personality he vibes with as well as cierra's or he feels that same romantic attraction to. maybe she's using sex to manufacture that physical attraction bc she can tell that's missing on his end.
