Interesting post, SINSULL. I understand your thing about the control issue perfectly, and I also have never married.

MBSLynee asked, "with less disapproval from society in general, has infidelity become more common?"

No, I don't think it has. As a matter of fact, I think it may be more common in societies where there is much greater dissaproval. I think that in those societies it's far more covert, as someone else said, but just as common, if not more so.
