Do you trust your wife?
If so, no biggie. For the strippers, the big "feather in the hat" will be the bride. Unless your wife is inclined to initiate something, she'll not get taken farther than she wants to.
For myself, I just don't "get" the whole pre-marital fuck fest parties.
One of the worst experiences in my life was in the Dorms at Colorado State University in 1992. A buddy of mine, a marine back from the first Gulf War, was getting married.
Bachelorette party was the week before.
Two days before the wedding, a video shows up at the dorms that shows his bride to be sucking off the stripper with a total mud shot. I mean full on porno shit with this "innocent" little woman sucking down the stripper's load right there on camera. And a note from a guy at the bar where the event was held (who was friends of mine, actually), saying "I video tape all of these things with the house camera up by the lights. Thought you should know."
My buddy went ballistic, it took six of us to hold him down and he had murder in his eyes. The guy knocked two people out cold during the struggle, and we literally had to "fight" him to keep him from leaving. It was fucking awful.
Bad, bad, scene. On the one hand, she obviously had no self control and it was better for him to know before hand, but DAYUM... what happened to having the respect for your lover to NOT put yourself into that kind of situation.
Ugh... I just as soon would skip this shit. But you set the precident going to one yourself, so you'll have to trust. Just try and read the signs when she returns and act accordingly.
