Why doesn't my wife want to sleep with me?

There may be many reasons for this, mainly including:

Your wife may be having an affair;

Your wife is frigid;

Your wife bothers you to smell;

Your wife was forced to marry you;

Your wife has ulterior secrets;

Your personal behavior bored her;

Your wife is a neat freak;

Your wife is mentally ill.

If none of them are, then your wife treated you like this on purpose, and you can find out the reason yourself.
