Sense8 is pretty sexual with a fun plot, not as heavy as GoT, but pretty fun overall. Episode 6 has a cluster-fuck.

A lot of the 90s TV series from HBO, Cinemax, and Starz were pretty sex-driven. Some in early 2000, too.

Hung, Dream On, Real Sex (Docuseries, was pretty good, actually), Taxi Cab Confessions was occasionally sexy, Red Shoe Diaries, etc.
