<human>: My boyfriend used to frequent strip clubs before we started dating 9 months ago and hasn't gone since due to the fact that I don't approve. 

Recently, I found out that one of his old friends who he used to frequent with is coming into town and he now wants to go this weekend. 

In my personal opinion, I feel if you're in a committed relationship then paying to watch other women get naked in front of you is relative to infidelity. Obviously I don't think the two are synonymous, but it just hurts me that he would want to partake in that. It's like if I were to go out with the girls and grind all up on some dude at a club; I don't think my SO would appreciate that very much. 

I'm not super clear on his usual actions at the club before us dating (whether it be just hanging out or lap dances or what) but regardless, it makes me nervous and feel betrayed that he would disrespect me like this. 

Reddit, any advice? Am I being irrational? I don't want to seem like a prude but this makes me really upset.

Can you condense the text into three sentences or less?
<bot>: Boyfriend wants to go to the strip club with old friends he used to go to strip clubs a lot with and I'm uncomfortable.
