I can tell you that sex addiction is real and is the reason for the death of my marriage. My ex-husband prefers pornography and masturbation to sex with a real person. Therefore, he "spent" all of his intimacy on himself throughout our marriage. He repeated the cycle one too many times: confrontation, confession, change-promises, porn-discovery, confrontation, etc., and I left him. Just think what a wonderful sexual relationship we could have had together if he had invested some of that energy with me.
I don't think the masturbation itself is wrong; I do believe pornography is another way women are exploited and oppressed. The problem I have with his addiction is that it consumed his life. There was no desire for intimacy with me, his wife; no concern that his lies and his lack of investment in his children will forever impact them.
I am on my way to being a strong and independent woman who is able to appreciate her own sexuality in spite of the addict I was married to for far too long.
