OP your dh does sound a twat. I'd be out of their sharpish if he can't even conceive putting your feelings above his own.
In regards to the lap dancing thing, I'm ok with it. I'm also ok with porn, well some of it, and have watched it with dh.
I've been with my dh for 25 years, since we were 15. So I'd say I know him pretty well and can gauge his feelings in regards to strippers/ dancers etc. I don't doubt I will say something which will offend someone on here but I'm simply trying to explain our feelings towards it, right or wrong.
To me and I think to Dh, the woman doing the lap dancing, or the porn or the private dance is just that a woman, any woman. He doesn't want to marry her, he doesn't want to know or remember all her little nuances and I doubt she gives a shit about his. He's the cash to her.
It is possible to emotionally detach from a sexual act, sometimes dh and I have sex as just 2 people an other times we have sex as husband and wife. Dh is still young and relatively attractive, when we go out I see him talking to other women, they flirt with him, it doesn't bother me because he isn't interested in them, he just wants me for the long term. So some woman gyrates her naked body on him but that's all it is, it's not an emotional connection.
About 20 years ago I went to a party with make strippers, I would be most aggrieved if dh thought that meant I was cheating on him?
I get I may be in the minority. Ideally my dh doesn't have sex with other people, but there have been times we have been on a break and this has happened on both our parts, I got over it as to me it's a physical thing. Just because this doesn't suit you it doesn't mean we are a bit thick or chavvy.
