I worked as a dancer for years. It was a fantastic job, and the notion we're all "tits and arse and no brain" is hilarious. Dancers are some of the most shrewd business women you are ever likely to meet. When I was there I worked with a trainee lawyer, a midwife, a girl who ran her own bakery, a forensic scientist, several beauticians, a physiotherapist...and many more. Right now, I'm a qualified accountant and a model. Believe me, the women are not exploited. The biggest misconception is that a girl is doing it to pay her rent/her way through uni/her debts off. So not the case, I've probably worked with 300 girls and not once have a met a "poor uni student." The men that come in are mugs and we fleeced them.
OP, having said this, I would go stratospheric if my boyfriend went to a strip club and danced. The thing is, you have two kinds of dancers. Clean and dirty. The clean dancers are the very pretty girls who attract guys no problem and who will pay to talk to them, dance with them. The dance will be fully naked, no touching, from £40 for one song up to £480 for an hour. It's not a sexual service, it's a dance. Then you have dirty dancers, who don't have the looks to earn money that way, so they perform extras. They snog the guys, they allow groping, nipples to be licked, touches of their vagina. It's fucking horrible. In any club, 50% are clean dancers, and the other 50% are dirty dancers. The two clans do not get on, the dirty dancers thought we were sanctimonious prudes looking down our noses, and we looked at them as whores and wondered why they didn't just piss off to a brothel.
Firstly, knowing that it would annoy you, he did it anyway so that's a lack of respect. But as a former dancer, if my boyfriend went to a club, I'd be fine if he didn't dance, but if he did, firstly I'd be cross about the waste of money as all the dancers do is bleed the men dry and it is absolutely not value for money, it's what their good at though, and what they're there for, and secondly, there's a 50/50 chance of whether he wanted to or not (if he got a dirty dancer) he may have had her bits rubbed in his face as it's her only way of enticing more money.
