The only way that I know, and the way that has helped me, is to give yourself the room that you need, the time that you need, and the honesty that you need. Don't rush because you want to be over it. It only creates insecurity and triggers.
When my goal was to be sexually intimate, or to just show affection, I could not see my real need. In fact, I walked all over my real needs. Sex isn't the goal. Understanding that there is such thing as a physical expression of love is what I needed to see. I did not understand this difference. I didn't understand love and how, in adults who are committed to each other, this love does express sexually. This is not the same thing as just having sex.
I need to give myself the time to see my husband's patience while I healed, and to see his commitment while he waited, and to see his decision to put my needs before his over and over again before I could understand love, and understand the difference between sexual intimacy (or even just touching with affection) that is the out pouring of love, and sex that is about self-gratification, or selfishness.
Until I experienced this change any kind of closeness was wrought with suspicion for me, and came with the expectation of being hurt and used for someone else's gain. It took alot of time to trust. And my husband had to show himself a man of super human self control and self denial. This change has just happened only two weeks ago. But it is phenomenal, and well worth the wait and the honesty it took. And it has remained. It doesn't come and go with my feelings. It has remained.
To sum it up: be really honest about your experience now. Don't try to be someone you're not, but wish you were. Don't push yourself to be healed. Don't ignore the triggers and push them aside. Be honest. Talk about it. You're significant other will be tested. But he has the opportunity to help you in a way that no other has. He has the opportunity to respect you and give you the experience of love through his patience, commitment, self control, and self denial.
I really hope things go well for you. I've only shared what I've found out for myself. It's not the only way I'm sure, just the way it has been for me.
One other thing. My husband and I both love Jesus. We are committed Christians and this had been the glue that has strengthened us through the hard times. Jesus Christ has been the source of my husband patience and understanding, and of my being able to heal and grow. He says, He will lead the blind by a way that they know not and will make the darkness light (Isaiah 42:16). He has done this. I have proved Him and He is true to His word. I have been led through a way which I knew not (healing), and where darkness once was the most beautiful light has risen.
I have tried therapy, but because I live in a rural area, I've found that it is just not practical. I drove two hours to my second appointment to find that my counselor cancelled. So, four hours of driving for a cancelled appointment led me to leave the idea behind. God and Christ have been my/our sufficiency.
