I don't get the sense that she's "raving" about them or deliberately trying to make the OP feel inadequate. She has made two comments - one from the club when drunk. The very fact that she rang her husband is, IMO, a positive one: she wasn't gloating, she was sharing a funny experience with the person most important to her who was in her mind at that moment: her husband.
As for the "peeing horse" comment, unless she's got some weird bestiality fetish, that's not a sexy image, is it? As others have said, it sounds like she's just verbalising the strange, almost comic element of what she saw.
It probably hasn't crossed her mind that the OP might be bothered by her comments, precisely because he almost certainly IS "enough" for her so it wouldn't occur to her that she might be making him feel inadequate because to her he isn't inadequate, if that makes sense.
I get the "what would happen if the roles were reversed" point, but I think there are so many differences between the way male and female strippers are respectively viewed, marketed, presented that I don't think it's as straightforwardly parallel a comparison as it might first appear.
