>FWIW: I've been to several Bible studies in my life and no one (including the one leading the group) ever said sex was a bad or for procreation only.

After sixties they usually keep mum about it :)

>>And, BTW, the definition of perversion is again given by the same religions - i.e. anything that doesn't conform to their rules is a perversion, ergo they think that sex is bad only when they think it is bad, otherwise not, Q.E.D.

>I don't know about this.... I think perversion is a relative term.... I guess that's what you're trying to say. :)

It is. Those guys first set the rules, then declare anything that's not by their rules as perverse, then say "all sex is OK unless it's perverse". Circular definition. So it's relative, depending on whose definition you use.
