Thank you.
1st the question: Yes, she knows my history.
2nd yes, I have been thinking about that trust thing also. But my conclusion is that I can trust, I just have to check better before. She is a very good person for having trust in.
3rd I am trying to masturbate less, because I know the effect. Perhaps I should try not to masturbate during some days to come back to more sensitivity.
4th very good idea to ask her for mutual masturbation. So SHE can make me cum, perhaps this is a help for her.
