I also find it really strange how asexual and/or platonic many of these people and couples have been... particularly on the guys sides. Calvin, Connor, Jeremiah, now Caleb too...all surprisingly prude for young contestants going on a televised dating show. The Calvin not even wanting to kiss Moira thing is particularly weird to me, like what's the big deal dude?? And Conor all giggly and infantile when a girl that he's ostensibly been attracted to wants to blow him? Bizarre. Maybe it's an editing issue at times. Like how we go from Kierstan and Carr seemingly happy in the shower to the next scene basically breaking up. With no real explanation from a Carrington talking head.
As for Lauren objectively I'd agree she's the most attractive woman in the house, not sure who else comes close (maybe Kierstan but her body is admittedly artificial). The men being attracted to Lauren for her h-to-w ratio, amongst other qualities, is not sexist lol. Just like a woman being attracted to a guy's broad shoulders, sense of humor, or yes even their wealth is not sexist. It's just gender-specific measures of sexual market value that have literally been desirable for most of homo sapiens' existence. You can thank these powerful forces of sexual selection for human traits like intelligence, creativity, and, badonkadonks.
Would love to see them send Mac and Connor home for being the worst, but I doubt they will.
