He never had the option to lie. I knew what he was going to do. I objected. He ignored.
Maybe he doesn't share your view on porn. He doesn't have to do what you want. Many people have barking views on a range of subjects, their spouses probably should not adjust behaviour to accommodate such views. A porn magazine is sufficiently mainstream in our culture that an NHS wanking room feels able to provide it. You view of porn is (quite literally) eccentric.
I would like to hear honest experiences of the men who had to do it alone in a hospital cupboard/toilet/cubicle. I think most would need some visual stimulation.
I have done it. The magazines weren't essential. However if DW had expected me to heed her opinion about using them I would have thought she was controlling, crazy or arrogant, depending on the exact reasons for her expectation.
For me the most joy-killing part of the whole exercise was a receptacle of considerably smaller diameter than (any adult) penis, making the procedure really difficult, as you had to hold the receptacle pressed against the tip with the wanking hand. The difficulty that created was a negative factor several times as large as the magazine was positive.
So you told him the porn was a deal breaker and he went ahead used it and admitted to using it ?
Looks like he wants the relationship to end doesn't it ?
Responsibility for ending a relationship rests with the person who does it. Not complying with ultimatums do not mean someone wants to end a relationship, it just means they refuse to be bullied. To illustrate with some hyperbole: if I tell my wife it's a "deal-breaker" if she doesn't give me all her money and a blow-job in the middle of the high street, and keep my word when she refuses, she's not the one who's ended the relationship.
