Libido......meh.....

So I have noticed lately that my wanting to have sex has gone down a lot.... like to the point where I find myself hurrying through a shower so my husband doesn't start sexy time....... I love him and am attracted to him, just more times that not I just don't want to have sex..... he uses the same curser to initiate so lately when I see them happening I avert and do something else.... help please!
