Q&A Is My Sex Drive Normal?

I have hyperarousal due to PTSD and I am the betrayed wife, we are 6 months out from D-Day. I have a lot of signs of PTSD. I only sleep 5 hours a night but have something else that is very strange and wonder if it would be related. I have always liked sex and we were together at least 3 times a week for 13 years. That has increased to 4-5, but in fact, I could go every day or more. I looked up stuff about coping and that is not it, as I do not want to when I am upset but I change on a dime and be ready to have sex within an hour or two. At first, I had a strong desire to know he still wanted me but now it is just a strong desire. I shared this with my spouse who thinks this is a burden, as he does not change on a dime. He has felt it was a coping thing until today. We made love and had a very good time. Did some stuff in the house (no conflict) and 2 hours later I was like, I really would like to be with you again. He now thinks it is kinda funny and I do not understand why I am feeling this way. We are in our mid 40's.
