Only replying because I have been asked.
Math not that I need to justify to you my own morals but "Why the prostitute exception to your rule on deciding the validity of a request for information? What is different about sex with a prostitute?"
I would be very upset to think a partner of mine paid a woman for sex. I consider prostitution and any kind of exploitation of women (such as pornography) to be very cruel. So I only want to be in a relationship with someone who shares my concerns. If my husband cheated I would, of course be upset, but to pay a woman to have sex is very offensive and wrong to the woman, as well as to me.
"And what difference would it make to know the details..." I did not say the details, about the sex, I meant only that it would be relevant to me if a partner cheated with someone of the same sex, just as I imagine it would be relevant if I were a lesbian and had a female partner who cheated with a men. I would not imagine my partner cheating, nor expect it, but if it did happen some things would make it worse. Such as longevity would make it worse to me.
Actually thinking a man might just exploit a situation in some way is not based on nothing. I's not necessarily true for the OP or her husband but talking generally about why people may not wish to say what happened exactly for me this may be a valid concern. As Sandy has pointed out this is not just a 'fear' or concern of mine. And I am not attempting to influence the OP, just discussing. The OP has their own reasons for saying or not saying what they want to, which for me is totally their own business. She posted here for input, so she is getting my input.
"I really do not understand the thinking behind your exceptions at all." That seems to be because you seem have one way of viewing all this, your way. I've made it amply clear I am not saying this is all true for anyone, I am expressing my thoughts, my opinion, that is all.
Sandy "However, imagine that you've wanted to do a certain thing for years and he always refused. It doesn't even have to be a sexual thing. Could be a trip to a flower show. Then you find out he went with the OW. Now whether he wanted to go or not becomes irrelevant...he went. He was more concerned about pleasing her, than his wife. How do you really believe that he loves you?
That is a really interesting point. Would the wayward spouse have the nouse to know that what they had done was a deal breaker, and knowing that was a deal breaker to confess to it? I think that is a great point but one which I would imagine would be quite hard to 'police'. So it is only the willingness of the wayward spouse to tell the truth and know what is relevant, maybe.
"One of the biggest struggles for many BHs, is the type of sex. The fact that they have wanted for example a threesome, or anal sex or whatever ..which was refused...then the OM who she's known for a couple of weeks gets it." If that something that comes up for males and females?
If someone is happy to have a three some in principle, how do they square that with the other person being unfaithful being such an issue?
Sandy it sounds like you provide a good service, are you a counsellor?
