Going for the threesome, long run -EV?

[squeek12]

I'm recently married, but my wife and I are still very young(23 and 22 respectively) and enjoy our share of drunken debauchery. I've noticed that when she gets smashed she gravitates toward some of our girl friends and gets a little frisky.

I know that at least one of our friends would most likely be up for it if the circumstances were right. The problem is that when my wife sobers up she denies attraction to women and gets a little defensive. She is also a little more jealous than the average wife/girlfriend.

Would going for the trifecta be a long run mistake. I think it would, but it would be interesting to hear advice/stories from anyone who has been in this predicament before.
