Spot on Perkins! You really shouldn't base on whether or not to leave the amoutn of times you have sex. How is your relationship other than that aspect? I happened to have the problem with both the sex and the closeness. Sex is a great way to feeling much more closer emotionally but it should not be all that the realtionship is about. That's what sex buddies are for!
But in all seriousness.... there is no magic number of times per week that is considered "healthy". I wish there was!

For me, towards the end, it could be once a week or once a month depending on his moods. Frustrating for a person such as I!
