Left wondering if my boyfriend took it too far at the strip club

I F24 and my boyfriend M26 have been together for almost 6 years, living together for 3. He’s the love of my life and we have talked about taking the next step -wedding, house, kids even- in the next few years. Everything’s been perfect until recently… he went out with his buddies for drinks one night, halfway through the night he calls me asking if he can go to the strip club with all of them. I honestly thought this was sweet that he asked and told him no problem, go have fun. He has gone to the strip club before, and we had the conversation basically saying I’m fine with it just be mindful of me, don’t be too much etc. Fast-forward, I don’t hear much from him just the usual snaps back and forth to each other of our faces and what we’re doing etc. Finally I hear from him and he says he’s going to be staying at his friends for the night and is planning to make a weekend out of it, he’ll be back tomorrow night or so. OK, no problem I have plans this weekend too, so I’ll see you when you get back. The next day we’re talking on the phone and he’s telling me about his night, the pub crawls, the dinner they had, then he gets to the part about the strip club. To sum things up, he met a stripper that he really liked there. She gave him tons of attention all night and he had a blast, she gave him extra long dances for free and even let him use his mouth to put money in her g string, and let him motor boat her and put money in her bra with his face. He talked about how strong she must be and how amazing she was at dancing in a way I never even heard him talk about me before… it really stings and just thinking about it puts a pit in my stomach. Am I overreacting even though I told him to go? What does this say about our 6 years together? Did he go too far with this?

Disclaimer: for anonymities sake I fudged all names/ages/ job titles etc just a little bit off.

UPDATE 1:

Hi guys I really appreciate everyone’s advice and takes on the situation, it’s all felt very overwhelming and to have so many people reach out and offer advice and to talk things through with has been amazing so thanks. As for my thoughts on all of this, as of now I’m still feeling a bit uncomfortable and upset. I do realize that my boundaries were vague and are most likely part of the problem however I just assumed that I never had to tell him any real guide lines as he’s NEVER been the type to do this sort of thing (I know he’s a guy and they are all the type sometimes lol) We are having a conversation about all of this tonight in an hour or so and I’ll do my best to answer everyone’s questions and share what he has to say the best I can.
