Not a bad idea. I think a return to old-fashioned behavior would end a lot of this thing. That is, two people get married, then they have sex but only with their marriage partner. It didn't prevent all men from cuckoldry but it worked for a very large percentage of them. All of this rutting around like wild dogs going from dog to dog to dog is a large part of the "paternity problem."
Except Reagan, as you know, is not a good reference in this context. More verification was needed in judgments of his work on family law reform.
