I'm not sure that I understand your question.
You're free here to write whatever you feel that you need to write -- if it's got to do w/ your recovery.
In regards to Step 4, on the Sex Inventory: The key words for me is "thorough" and "as we went back through our lives."
My personal opinion is that we should go all the way back to "as far back as we can remember" -- on everything in the inventory: Resentments, Fears, Sex Conduct, and Harms to others.
I do cautions -- especially with Sex Conduct -- that these be kept very private and secure -- where you are reasonably certain that it won't fall into the gaze of someone else -- especially, if you are in a relationship with them. And, that you feel reasonably certain, that the person you share this with in the 5th Step can be trusted -- AND that they are not your spouse or significant other. There are many reasons for this -- for your well-being and for the other persons well-being.
It's best to keep the entire inventory secure. If it's something that you wouldn't want someone else to know (which most often it is) -- write in a code that only you understand. Use symbols or something else to represent names or events or situations -- that you understand -- but they would not understand.
The only person that should see your inventory is your sponsor -- or whomever you do your 5th Step with. And, they have no need to read your inventory. The 5th Step is verbal -- with you sharing about what you've written -- and not them reading what you've written.
I hope that helps. If you need further clarification, or have other questions, or if I didn't answer your concerns, please continue to ask.
