I don't think i would throw a hissy fit, but i dont think i would like him getting lap dances. If he were just going to a strip club, thats fine. It's when a girl is dancing on him and touch him, thats what i would hate. If its for his stag, by all means... but apart from that, no thank you!
That being said, I'm lucky. My Boyfriend has no interest in strip clubs at all. He said he kind of got over that in his early twenties, and he finds them more sad than anything. I suppose i don;t have anything to worry about. Even so, the thought of a stripper dancing all up on him makes me angry.
