See the NA Step Working manual for an example of the kind of questions one considers in a 4th step: http://gssana.org/books/na-step-working-guide.pdf
Some examples of the things from that manual that I'm curious to know how others responded to and shared with their sponsor:
How was my sexual behavior based in selfishness?
Have I confused sex with love? What were the results of acting on that confusion?
How have I used sex to try to avoid loneliness or fill a spiritual void?
In what ways did I compulsively seek or avoid sex?
Have any of my sexual practices left me feeling ashamed and guilty? What were they?
Why did I feel that way?
Have any of my sexual practices hurt myself or others?
Am I comfortable with my sexuality? If not, why not?
Am I comfortable with others' sexuality? If not, why not?
Is sex a prerequisite in all or most of my relationships?
What does a healthy relationship mean to me?
and:
Before we finish this Fourth Step, we should stop and reflect: Is there anything we've
missed, either intentionally or not? Is there something we think is so bad that we just can't
possibly include it in our inventory? If so, we should be reassured by the fact that a
multitude of NA members have worked this step, and there has never yet been a situation
in anyone's Fourth Step that was so unique that we had to create a new term to describe it.
Keeping secrets is threatening to our recovery. As long as we are keeping a secret, we are
actually building a reservation in our program.
Are there any secrets that I haven't written about yet? What are they?
