While yours wife lack of sex drive in her younger years was probably due to emotions and hormones - the exact same thing is happening now, but this time with a more positive side effect for you the man.... when a woman goes through menopause she looses a lot of the estrogen that controlled her so strongly and made her moody, and now she is driven more by the high levels of testosterone that created an over drive for sex in her male counter part - she has now joined the male ranks for wanting sex.

Count yourself lucky and enjoy the change...... w00t w00t.
