So, there is a real cause and effect mystery with this story. Did David develop this "condition" after he married hottie Tea Leoni, or did he marry her because he already had this problem?
Either way, kind of hard to fell sorry for him when he comes home to this every night:
Well, I think there are conditions where sex is an addiction that either can't be broken to an unhealthy end or it becomes something extremely obsessive (i.e. chronic cheating). Might be part of the relationship or whatever factor figuring in to such thing. Of course, frequently having sex isn't an addiction, but an addiction most wouldn't mind, now would they?
