"have a naked woman rub herself up on him for money"
OK, I'm a man, have not been to any lapdance clubs, and the strippers I've seen were at a pub where a bunch of staff where I worked used to have a Friday drink, 25++ years ago. (That bunch of staff being equally split, male and female).
No 'rub against' anyone when naked, all stripping was on a stage and given crowd of working guys gathering near stage, having a bite to eat and a lunchtime drink, we could just see her from the chest up, if we were lucky, and to be frank, we were more likely to be chatting about holidays or whatever.
Maybe some of the stag parties (esp in Europe) go a lot further. I'm not dismissing just curious. Can understand your view, OP, and think it is down to your partner to tell his childish mates that if they taunt and carry on about a stripper then he'll simply not bother.
They know they are winding you up, he's not amused, and whatever they think, it's you he loves, and he can happily live without them in future, if they want it that way.
I think it would show them he has morals, and a backbone, and they're insignificant compared with his love for you. If you think he would do it, show him the thread. It's clearly giving you a lot of heartache and concern, and he's not responsible, but his male friends, but there's being part of the crowd and there's being able to "break the mould".
I'd hope they grew up, took more notice of other people's views and adjusted their behaviour accordingly, but somehow I doubt it... so many men, in their 20s, 30s, 40s and more, can still show tremendous immaturity.
