You might be a sex addict. If you look at the website
#SLAA Online Group of Sex and Love Addicts Anonymous - Home, you will find a list of questions that might help you identify yourself as one, or not. Only you can decide, but you have to be honest with yourself when you answer the questions. If you think are, or may be one, there is help. It's a sickness that has a cure. I personally am a Sex and Love Addict and early in my 12 step recovery program, and hopeful for the future, although I have a lot of very dark days.
I suggest you take this seriously, but nobody can do it for you. My problem is costing me a marriage, all my savings, what little self respect I had, and the depression could kill me, but what really hurts me is knowledge of the pain I have caused other people, namely my wife and daughter.
Good luck, and peace...
