>That's interesting. I always assumed sex for young women was taboo back then due to the risk of pregnancy out of wedlock, and not necessarily from any concern for the woman's emotional state. But I like your reasoning better.

That was also part of it. Unsurprisingly the whole thing is rather multifaceted.

Your Montgomery example is a good example if what I meant. Innocence is easily lost and often under painful circumstances. Which is also why it's valued and people desire to protect it.
