I guess i need to make an appointment

So here it goes. My husband and i sex life has gone down majorly. Its all my fault. I know i had a baby almost a year ago. Before we got pregnant we had sex anywhere between 2 to 5 times a week( depending how busy work had us ). Now its 2 to 3 times a month maybe.

Hes starting to get annoyed and upset. Im just never in the mood. When i have sex with him its because he really wants it and i know i need to satisfy my husband. Sex is extremely important to him. I really want to be in the mood im just not anymore. I feel so bad.

My husband googled, he said its normal from anywhere from 3 to 6 months. So he thinks its a good idea to make an appointment to see whats wrong with me and i agree.

My question is....has this happened to anyone else? Has it happened this long? Or shorter? Or longer? What did you? Im making an appointment. I dont want to lose my marriage over me being broken. Thank you for any input.
