It's ridiculous to suggest that ALL men watch porn. Some will obviously have strong reasons not to (against it for personal/ethical/religious reasons, low sex drive in general, just doesn't do it for them, etc etc). But most do, and several lie about it to their partners, if they know they wouldn't approve. Therefore
some women who are 100% sure their male partners don't watch porn are wrong, just as some women who are 100% sure their partners would never cheat on them turn out to be wrong. Some of the posters on this thread saying their husband/boyfriend definitely doesn't watch porn might be among the percentage of women who are wrong, but almost certainly not all of them.
That said, I don't think it's the same as saying "how can you be sure your partner doesn't secretly go badger baiting/buy expensive watches/love chocolate when he claims to hate it" etc. Sex is a fundamental instinct for most people and there's a strong taboo around discussing it completely openly - lots of people aren't comfortable sharing certain fantasies even with their partners, for example - that doesn't exist for the other things. In fact we're almost encouraged to lie about sex in many situations, if only by omission (your colleagues don't want to hear a graphic description of your last wank), in a way that would be totally weird if we did it for something like food preferences. So not really comparable IMO.
Well, the badger-baiting comparison was mine, and on reflection I do agree it was a silly one. My partner used to know some people who went baiting (as did my dad - one of dad’s friends possibly went to prison for it in fact, tho this was long ago so I may be making this up!) so it wouldn’t be entirely an implausible thing for either of them to have done (except that it’s awful and they aren’t ) but I agree, if he wanted to go baiting he would have to do quite a bit to organise it, AND give me a convincing cover story (not hard as I don’t expect to know where he is every hour of the day, but there would still be some thought involved), and b) just take loads more steps to do it, like hooking up with old acquaintances, travelling to a suitable place, etc. Plus we don’t even have a dog.....
Whereas obviously with porn he could, in a moment of weakness, just make a couple of clicks on his phone and there it would be.....
Still don’t think he does, tho. And that’s not me being insanely naive - when you have been married and divorced as many times as I have, you take EVERYTHING that is said to you with a pinch of salt. My balance of probability is still that he doesn’t. I would plausibly believe he did other bad shit, like having a ONS behind my back, sooner than that. Not because porn use is the most heinous moral crime known to man (it isn’t that, tho it still ain’t great!). Just because of what I (think I) know of him.......
