I am about to be 36 years old. I have had problems with my sex life with my husband for about 2 years now. We have been married for about 3 and a half years. It started before my ex got out of prison, and the lack of attention drove me to the attention of my ex. I didn't have sex with him, but I wanted to. My husbands excuses vary. He is tired. His testosterone may be low. I lay like a lump on the other side of the bed doing nothing to start the sex. I don't know what to do. We have a daughter that came from him, and my first daughter came from my ex who left me after 11 years while I was 7 months pregnant.
