I think I have a sex addiction. I masturbate at least 35-40 times a week, I watch porn to masturbate and find it difficult to keep an erection during sex, but not to porn. When I see almost any woman now I fantasize about them. I often think about cheating. I am almost consumed with this in my life. What do you think? I need help, but it needs to be private so I don\'t lose my job.
