For the past few months, whenever my husband and I have sex, I'm REALLY not that into it. I find myself thinking "when is this going to be done?" or "how can I speed this up?" I don't know why I feel like this! When we were dating, our sex life was insane! We could go for hours, and now I find myself hoping he finishes quickly so I can go to bed. My husband and I have a great relationship, work is good, no major stressors affecting me to the point where it would make a difference in the bedroom. I haven't changed anything in terms of diet, birth control, etc. my libido just seems to be nonexistent. I've tried imagining him as a celeb crush which sometimes helps, but not really. Can anyone help me out and suggest what may be wrong?
