My husband wants a baby, but is never in the mood

Hey everyone, I need to vent a little. My husband wants a baby but is never in the mood for sex. He has been like this since we got married. We have sex 1-2 times per month, 3 if I am really lucky. Once he is things are fine, but I am tired of asking for it all the time. I am also tired of being the one to check my temperature, check my cervix, do my LH tests, and pregnancy test after pregnancy test....AND on top of that get him "in the mood"... it is exhausting. Does anyone else have problems like that???
