S1E1: a man has sex with a woman whom he mistakenly believes to be his girlfriend. A plot in season 2 involves a clone's ability to reproduce being exploited by a cult. S2E5: rape on-screen. The rape is never addressed after the fact, and this is likely because it involves a woman attacking a man rather than the other way around. Although not explicit, the scene is unambiguously not consensual. S3E1: a woman is groped by a man. Season 4: an ongoing sexual relationship between an adoptive mother and her son. This may not be technically considered incest, but a character has a relationship with the woman who both created him (as a clone), and then adopted him.
