> Sex was one of a few available entertainment options.

I honestly wonder, what's so much better about today's entertainment that people prefer it to sex?

I was also born in communist Czechoslovakia. Yes, it was dull, although I was too young to speak for sex. From what I heard, it was a weird mix of conservative and liberal morality.

I personally think that people were simply more content with relationships they had. Today, people are dazzled by the paradox of choice, because their life heavily depends on good choice of the partner (as I already remark elsewhere in this discussion).
