I think this is more of an issue of the Christian dating pool having already been sexually corrupted by the world. Even if a young person abstains from sex they are still bombarded with such sexual content and imagery that I can imagine it warps ones view of what sex is and what it's supposed to be before they ever even have it.
Sexual frustration within marriages is nothing new and something I imagine has gone on since antiquity. However only relatively recently has sexually gratification within a marriage been so important, and the bar for sexual contentment been set so high, that it actually ends so many marriages.
I don't know if the solution is to teach Christians how to be sexual stallions and give their partners better and greater orgasms but rather teach them to keep a proper perspective on what sex is and what it's for. I believe we're supposed to enjoy sex as Christians but I'm not sure if we should be indulging in such lust that our Christian women, even our wives, should be orgasming so hard they begin contorting their faces and growling like demons lol. Maybe that's not a good thing.
I was actually speaking about Christians who have remained totally chaste throughout life up until marriage and who have seen no pornography or even rated R movies in many cases.
There are problems stemming from the examples you mentioned but I was not bringing up those in my post.
I don't think it has to be either accept the sexual limitations of your marriage or chase the most intense orgasm you possibly can. Those extremes are a false dichotomy.
As far as sex not being about pleasure for most of history well that is true for women as many men who are raised chaste have no idea what or how a woman within marriage can reach an orgasm-- something God designed with the creation of the body I might add.
I have been exposed to tragic sexual experiences on the part of married couples who were raised chaste stemming from all kinds of problems-- mostly closed mindedness and puritanical approaches.
I have seen couples where the mans penis is just far too large for sex to be comfortable for the woman. I have seen couples where the mans penis is far too small to be pleasurable for both partners. I have seen couples where one or both partners feel dirty or wrong or bad if they enjoy sex too much. I've seen many other problems too.
None of these marriages were headed for divorce but just a few sessions of Christian sexual counseling, giving the couples vitaly needed information about human anatomy and different ways to achieve sexual union have made a world of difference for them.
I really feel for many couples who are right now going without a mutually satisfactory sexual life where both couples are in love, fully committed to one another in faithfulness and the Holy Spirit is with them.
