Excellent review, is the second I read about it, yours seems quite complete. I must add that just before reading it I had just read a publication of another steemian that dealt with sexuality and how we continue to consider some things as taboo, so I came somewhat predisposed.
I will consider the series, although, as you say, obviously trying to bring sexuality in a much more open way when it comes to 16 year olds, and taking into account the increase in early pregnancies, is somewhat problematic.
