I too use sex as a coping strategy. In my case the physical masturbation is quite tame, but I use psychological abuse and sexual humiliation. I also have to regress to myself as a child, being humiliated and abused by an adult with control over me. A lack of control is a key element in my suffering during the fantasy. I have continued this behaviour since adolescence, and throughiut my adult life. This all seems to stem from years of surgery on my genitals throughout my childhood. Its all a bit concerning, and embarrassing. But being new to this forum I've been amazed at how open some folks are, which is a great help and I've benefitted from some amazingly kind and supportive members. Its helpful to learn that I am not alone in using this type of negative coping strategy, makes me less of a freak. So I relate to how you feel. I certainly view it as self harm.
