My wife wants me to be intimate with another woman. Is this normal?

Maybe it turns her on to share ... That being you with another woman while she watches.  But it needs to be something you are both comfortable with.  And is it normal, well there are some couples who do this, but most don't.  So if you are agreeable to this want of your wife then it doesn't matter if is is normal or not.  Agree?

Watch it she may be setting you up for her to have sex with someone else. Threesomes are one thing but if she wants you to be alone with someone else thats another. Something fishy here.
