I think the women seemed almost like a parody to the boys. Neither is real attractive nor in very good shape physically - not for exoctic dancers, at least. Mangum is downright ugly. I believe Reade was being polite when he said it was boring. I think they relayed their general disappointment and Kim knew there was no more "money to be made."
I have said from the start, and still maintain that there was NO WAY any of these guys would have touched these chicks even with a broom stick. I think they were surprised at what arrived at the house and were, as one of them said, "sheltered". I think that the women picked up on their being grossed-out and it Kim quit dancing and Crystal was wasted and mad. The pin-dick comment probably came from that.
Back in my day, I went to a "girls' smoker" where they had hired a male stripper. I thought I had been around the block and would be amused. When this guy started gyrating, all I wanted to do was die or slide out the third story window. Yuck. The actuality is oftener more crass than one would imagine and the boys seem to have had a similar reaction.
