I used to be in a band and we hit the road all the time. On these trips there were women coming up to us all the time. The single guys in the band hooked up with these girls , and I always had good stories to tell my W afterward. So, yes, in the old days (first few years of marriage) shoes was on the other foot and she had no trouble with it.
Since then we have a little daughter and I'm not in the band anymore, just the day job left (I'm the main breadwinner). I still have full leash to go on any man vacations I see fit, but my buddies and i go canoeing and do outdoor stuff instead of "partying."
However, I'm still uncomfortable when the shoe is on the other foot, which given our record together, seems unfair. I'm in counseling to understand why I have this trust issue. All the usual stuff about familiars, fear of a, etc.
Putting my foot down and saying "you can go to the beach but please stay home from the bars" would be a recipe for disaster and she would think I'm being controlling.
