Why do I need alcohol to have sex (11m postpartum)

My daughter is almost one, and I’m still nursing. I love my husband very much and am indeed attracted to him and we had what I would consider an above average per week sex life.

Our daughter is the easiest child, but I also am with her every day. It feels like I need two beers to even calm down enough to be able to want to be touched/snuggle/be intimate of any kind including sex. This was absolutely not the case before I had a baby . Is this normal? Is it bordering alcoholism? Is it alcoholism?
