Hi, one thing you could do if you want to make sure and preserve orgasmic capability, is learn to have orgasms through methods other than friction.
The system won't let me send you PMs, and I don't want to get too graphic here, but if you search youtube for "breathing orgasms" you might find something useful. I found one woman on there who teaches classes that look at least similar to the methods I learned a long time ago. I did learn a Qi Kung method (which actually works for XX, XY and variants). Basically it involves breathing out and rolling the belly downwards until all your energy concentrates into a tingle in your genitals. That feeling builds up into an orgasm the way that friction normally would. Also, I am pre-op, and this is a non-ejaculatory, very free and "full body" feeling as well (without any kind of "control" involved).
The other method I learned is breathing in and arching the back, breathing out and bowing forward (reverse of an arched back, like the cartoons you sometimes see of the hippy flute player). This takes longer and is harder for me, but seems to require less "finesse" and was used at group "sex camps" at my previous Kung Fu school. The nice thing about that method is the girls can sit on the boys laps and you can time it in opposites to each other, along with deliberate connective breathing with your partner can produce a wonderful experience together.
Since learning these methods, I barely do it the other way, and I've taught a few lovers the method and they also liked it. They both also tend to build a charge in the genitals so whatever FRICTION you might wish to apply would be increased in ability as well.
I would assume this would work regardless of how your surgery went. Also, if you can get REALLY CLOSE through saaaay, nipple stimulation, then you would probably be able to push it over the edge post SRS, even if your feeling was reduced.
So, look into creating pleasures that don't depend entirely on the genital sensations and you will be a long way "there" by the time you get there. We don't have a way to PM each other, and I don't want to get more graphic than all of this or breech anyone's comfort area, but I can say that there definitely are ways to do what I've described, and I think it should at least HELP. Whether it works post SRS or not.... well, ask me in a couple of years (fingers crossed :-) )
