i didn't grow up with much of that, but the missus had a state-mandated curriculum called Postponing Sexual Involvement forced upon her in school - so all the kids had to go through it, not just the offspring of the religiously repressed (then again, one could argue that everyone in that state was the offspring of the religiously repressed...). sounds like what she went through with PSI is about the same as these religious folks: social pressure to conform, mixed messaging wrt mainstream media, public shaming, poor preparation for what your body was going to experience, etc. sounds awful.
Jesus.
that appears to have been the problem, yes.
