my friend, i have to ask you....why do you NOT want to talk further to your bishop?
you must understand, an addiction does not simply go away. as sincere as we are about feeling repentance, we are just as sincere at looking at some way to continue the addiction, usually through some rationalization or other.
i would urge you to continue your talks about it with your bishop AND seek out a 12 step group dealing with sexual addiction.
just so you know, and i have posted a bit of my own history here before, i was sexually abused VERY young and then throughout my teens. i was introduced to hardcore pornographic photos when i was 7.
all of my abusers were adult females. that along with the severe mental and emotional abuse from my own family, mother and older sister (father died when i was 5), really messed me up in so many ways.
i am now 58, have been through LOTS of therapy, counseling, prayer, religious study and application of meditative techniques. i do happen to know a bit about what you are dealing with.
and if you think that you're not that bad because your own history was NOTHING like mine, you're fooling yourself. you have an addiction to sex, plain and simple. you need help in dealing with it. do not be ashamed of what you need to do. embrace it and deal with it. it is my prayer that you are able to, in Jesus name i pray, amen.
