Masturbation During Marriage

Kristin • 23 year old wife and mother of one. TTC #2
My husband and I are strong believers in what we call self love. We both perform self love on a regular basis and are very open with each other about it. We still have a very active sex life together but feel that everyone needs "alone time" as well. This being said one of my close friends just LEFT her husband for watching porn and masterbating with out her. She stated that it was just as bad as cheating. Are my husband and I odd in how open minded we are on this subject?
