The British dramedy centers on Otis (Asa Butterfield aka the boy in Hugo), a high school student who decides to make some extra cash working as a sex therapist for his fellow classmates, as his mom (played by The Crown’s ibble dibbleing Margaret Thatcher, Gillian Anderson) is an actual sex therapist.
Better than a thousand YouTube tutorials or Cosmo articles, this show dives into all of the nooks and crannies of sex, highlighting homosexuality, bisexuality, pansexuality, asexuality, douching, scissoring, masturbation, fellatio, crossdressing, erotica, roleplay, fetishes, vaginas.
