I edited your post so that I could respond more easily to the points you raise.
1 - This proves my initial point, that it is not rare. Many women are experiencing the fallout of being abused by their husbands and many men are addicted to porn. That is all that I have asserted. That “many” women and men have been affected by this problem in their marriage.
2 - Why do I need to provide “hard data”? It is a reality that is commonly known that women can and do get injured if they are penetrated before their bodies are adequately prepared and natural lubrication is present (or artificial lubrication is applied). Labia can and do tear, as can the tissue of the vagina. This happens all the time to rape victims, but it also occurs often enough to women who are coerced into over frequent or rough sex. This is why men need to be educated prior to marriage about how to lovingly prepare their wives for intercourse.
3 - I have not failed to consider anything, silentfactor. My initial and subsequent posts have all been about a valid reason why a wife may refuse a quickie. I am making no other point.
4 - bolded red statement of yours is offensive. Even if problems might be psychological sometimes, that does not mean that a wife is guilty of any kind of sinful attitude, especially the one you describe. And in case you missed it earlier, I know nothing about 50 Shades, so whatever point you are trying to make about it here is totally lost on me. I don’t even know what “going all 50 Shades on her” might be referring to.
5 - Your last point assumes too much. I do know that men do listen to women. Amazingly, some husbands do listen and care deeply about their wives and still accidentally get it wrong when it comes to understanding female sexuality. They can do harm to their beloved because of ignorance. When they know better, they do better.
And just in case you missed this other point earlier, too, I am not putting down men, and I am not painting victims out of women either. I am simply acknowledging a reality that is present, even in the Christian community.
I have tried several times to make my point clear, but just in case it is not clear what I am speaking about, here it is one more time.
While quickies might be appropriate in some marriages, and even mutually enjoyable for the couple, there do exist marriages in which quickies would be inappropriate, due to the fact that the wife has experienced sexual abuse (either at the hands of her husband or someone else). So we shouldn’t make judgements about the motivations of women who refuse to participate in quickies.
There it is. That is the point that I have been attempting to make. That is it.
