My daughter watched all the episodes of the first season and loved it, I only kept an eye out for the sex scenes in one episode to get through. From the rest despite the blood spilled in each episode we could watch it.
The plot is interesting, and how it develops too, everything is an enigma at the beginning but you can understand "everything" before the last chapter of the season, we'll see what happens in the second when it comes out.
The sex scenes are somewhat strange to perceive, I'm not saying they are bad, on the contrary because they were handled properly, what I'm trying to say is that this series with its animation style and some characters has that feeling of being a family production and it is not, as you say, scenes of sex and violence, but nothing exaggerated, nor so explicit.
I apologize for the lateness of my answer @cjlugo
