The man wrote: "We have been dating for around a year, and have never gotten into a serious conflict like this."
Reddit users had little sympathy for his plight, and several insinuated that he had cheated.
Hummingkindle wrote: "I'm neither religious nor conservative but if my boyfriend went to a party with strippers and stayed for the stripping bit he would most likely be dumped.
"You don't need to be religious or conservative to have boundaries where you don't want your boyfriend around strange naked women."
Somebody else said: "If she won't look at him and doesn't want him touching her, I think he's already been dumped and just doesn't realise it."
Other women agreed, with one writing: "Refreshing to know I'm not the only person out there who thinks like this."
She then said his action amounted to "adulterous behaviour".
Reddit users also pointed out that strippers at home are typically "much, much raunchier than strippers in a club".
In a reply to another Reddit user's comment, the man said he'd told his girlfriend all of the details of the night, and that he had felt uncomfortable about the stripper and so "hung out back".
His girlfriend told him he should have left the party at that point, and that he had crossed a line by staying.
Some Reddit users did empathise with the man, with one posting: "All that you can do at this point is apologise and say that you didn't realise it was a deal-breaker to her."
One made the point that he didn't invite the strippers over himself and "(presumably) didn't engage with them".

"However, it's not fair for her to be angry with you when you didn't know there would be strippers and you had no idea that strippers would be an issue.
"Now that you know, you should avoid strippers going forward."
Another user asked: "Does she wish you treated her the same if that happened to her?
"Pretty unfair of her to treat you like scum for this situation."
Somebody else said: "If it wasn't his decision and was for a bachelor party, does it really have to matter for that one night?"
They ended their post by saying that they wouldn't care if their boyfriend saw a strip show at a bachelor party - just as long as there was no touching.
