I finally got around to transcribing Joyce & Dr. Harley's response to my question on pre-marital sex. For those who are interested but haven't been able to listen for some reason, here's what they said. (I made a few edits for clarity, and I underlined words that they emphasized while speaking. If you want to hear the broadcast, the link BrainHurts provided is
here.)
Joyce: Here�s what he has to say:
Several posters and I were having an interesting discussion on the Marriage Builders forum. The discussion was about pre-marital sex; several people felt sex should be reserved exclusively for marriage, others felt that evaluating sexual compatibility before marriage is a good idea. Much debate ensued and went into an argument over moral values.
We don�t want any arguing on the forum there.

And then he quotes from your book Buyers, Renters & Freeloaders; he says,
In your book you state "since leisure activities and sex are two of the best ways to enjoy time together after marriage, incompatibility in these areas can make it very difficult for a couple to create a fulfilling and permanent romantic relationship." It seems from that statement, that incompatibility in those two areas should be determined prior to marriage. But several posters on the forum feel that you do not advocate premarital sex. Many posters and I are anxious to hear your views on this topic.
And I�m just going to add here, probably so they can put this to rest!
Dr. Harley: It�s a multi-faceted issue. If you have pre-marital sex prior to marriage, you have the same argument that you�d have with living together before marriage. In other words, let�s kind of test out our relationship and see how we get along when we�re actually living together. And there�s a sense in which pre-marital sex has many of the same components as living together. In other words, it�s very
intimate, we�re getting to know each other very, very well at a very basic level, but it�s a trial run. We�re not really doing this necessarily with a commitment to each other, we�re just doing it to see how we work out. We already know that living together before marriage is essentially a disaster.
Joyce: Ok, they�re asking for statistics that show correlation, either positive or negative. So are you saying that information that�s come out about living together before marriage, which has been negative, would also be applicable to sex before marriage?
Dr. Harley: I�ve not seen articles about sex before marriage, but I�ve seen lots of them on living together before marriage, and in spite of the fact that we see living together before marriage tends to create a violent relationship, 80% of all domestic violence is related to living together before marriage, and yet the numbers are increasing. So in spite of all this evidence, we�re seeing more and more people living together in spite of the fact that we already know it�s a very dangerous relationship, one that rarely ends up the way people thought it would.
Joyce: And sex now too, it�s not even thought of as a
wrong thing, so I�m glad he brought this up because it�s so prevalent.
Dr. Harley: Like I say, there�s a lot in common between living together before marriage and sex before marriage in that it�s a trial run, see how you get along. Now, I recognize that there are a lot of people that have sex with just about everybody they date. One of the clients that I had, when he met his wife for the first time, he wanted to have sex with her, and she didn�t want to have sex with him because of her religious background, and he said �Listen, if you don�t have sex with me tonight, there will not be a second date. Every woman I�ve ever dated has sex with me whenever we date.�
Joyce: Well I hope she said what I would say, �well then there�ll be not a second date!�
Dr. Harley: No, there
was a second date, she
had sex with him that night, and they ended up getting married, and they have had all kinds of problems ever since.
Joyce: But it didn�t necessarily relate to that decision.
Dr. Harley: It did in a sense because once she had sex with him, he didn�t feel that that meant he couldn�t have sex with somebody else. He did not commit himself to her. So he not only had sex with her, he had sex with somebody else too.
Joyce: While they were dating?
Dr. Harley: Yeah, and that�s been an issue throughout their entire marriage. So the basic feeling that I�ve got is there�s a lot of downside to sex before marriage. Now, there is some
upside. In other words, like he says, are we compatible sexually? There are many marriages that I�ve come across where they didn�t have sex before marriage, and then at the time of their honeymoon, it turns out that one of them just wasn�t interested in having sex at all. So, what do you do then? Or, the first time you have sex, it turns out that the wife has vaginismus, and she finds it extremely painful. She�s never had sex before, the first time she makes love it�s terribly painful. It�s one of the examples I use in my book Love Busters.
Joyce: But all of those things could be overcome through education, medication, and getting to the heart of the problem. It doesn�t mean it won�t happen eventually.
Dr. Harley: Exactly, and my argument has always been, I�m an advocate of avoiding sex before marriage because that�s what it says in the Bible to do. The Bible makes it really clear. It�s a moral decision.
Joyce: Outside of moral values, do you have any evidence that it should not take place.
Dr. Harley: From my own experience as a counselor, even though I�m biased, I think that people should wait until they�re married to have sex, and that eliminates a whole
host of problems: pregnancy before marriage, it eliminates the problem of venereal disease, and resentment afterward, because if you�re going to have sex before marriage, chances are you did it with somebody else besides, so there�s probably a line-up of people. And so, my basic position is, that of all the people I�ve counseled, the ones that didn�t have sex before marriage have
much fewer problems, much fewer problems in the area of
sex, than people that had sex before marriage. And as in the case of living together before marriage, you don�t really get to know what the person is like when you live with them before marriage, and you don�t really get to see if you�re sexually compatible if you have sex before marriage. Lot�s of people have sex before marriage, and within a year after marriage they�re not having sex with each other anymore.
