I am also one of Dr. Bower's girls, and it was about month eleven and a half that my clitoris once again began to have sensations I could relate to touch pleasure in the "O" territory, at month 18 it is still fine tuning itself, but it's making progress.
As far as honest to gosh Orgasms though, I have had several all on my own, but they are FAR DIFFERENT from what I knew as a male. My body as a whole must be involved and put together for getting the O. My first O type sensation involving my vagina was at about month 3 right after I had gone down to two dilations per day. It basically involved rubbing the curved end of the Dilator in and out with pressure above the inside of the vagina near the front, and even twisting it completely 360 degrees. I was able that way to get a fluid discharge from my urethra that was close to an ejaculation sensation. I had massaged the G-spot without realizing what I had done. The first time felt more like a urinary accident, but then I identified what it was.
Use your dilator as if it were a sex toy, that is fine, and another surgeon calls it Dynamic Dilation. Since you are at one time per day by now, take the time to possibly even do your hair up, and wiggle around a bit in a sexy nightie before doing your dilation. Have your BF with you as you do it, and maybe let him "take the controls" and just relax as he does it

. Or let him have his try and then finish a longer session with your green or orange friend. You have the longer staying power.
Set a mood for doing it, and let your fantasy run wild

. Your nerve healing and re-orientation will take time still, but it keeps getting better. Not all orgasms are created equal, and none are what we used to know as male. I have used an electrical "toy" a few times, including one I can hold in my hand with the dilator that makes me giggle and my nose wrinkle.

Do call Dr. Bower's office if you are still worried, Robin is great about helping with this stuff and even the new nurse in their San Mateo office is able to help plenty. Another Sister of ours had her surgery back 4 months ago and she is very happy over the help and response they give her.
