What IS good, and how do we determine it?

The problem is that most people won't practice abstinence because sex is such a powerful urge. Sometimes it seems  that some religious people are so focused on not having sex that they actually think and talk about sex a lot more than those of us who could care less who sleeps with who.

That would be because a supressed need gets only stronger and can have some pretty nasty side effects as every psychiatrist can tell you.
