In response to this: "The rebel keeps lurking around her bedroom window – and I think we're supposed to find this romantic...a man who's forever 18 (sure) stalking a camisole-clad teenage girl." 

What you haven't commented on is that the show goes above and beyond to establish the young woman's enthusiastic consent. Raven has complete control over the relationship between herself and Strat - every moment of physical contact between them is initiated by her. When she expresses any moment of sadness or doubt, Strat gives her huge amounts of physical space and waits to be invited back in. I applaud this show for giving audiences a very important social lesson in how the sexy rebel boy is even sexier when he asks permission, pays attention to his potential lover's queues, and does nothing without enthusiastic consent. Throughout the show, female-presenting characters (Raven, Zahara, Sloane) are given agency to turn down unwanted sexual advances.

I think you missed something.
