I do not know the answer, but feel deeply about your anguish and fear of what must be happening.
I have not pinpointed the exact place where my orgasms (the few for sure) most affect. I know that without the prostate, there will not be ejaculate during orgasm, but in my pre op days, most of my "orgasmic energy" came from my breasts and upper thighs, and while there was ejaculate, it was by far the least element of my climaxes. There has been no change in the nerve stimulation issues above my waist, and at 11 months PO, the nerve sensations in the vulvar area are still processing their new information, but it is not complete yet.
Based on the limited response I get from the prostate ejaculate these days, but the basic feeling of a climax and release of other nerve areas, my guess is that you will have some type of orgasmic climax, but it will be different than you have experienced to date. You will be able to have pleasure from intimacy.
