Working from the premise that you are alive (there is a book titled "Dead Men Don't Have Sex", which is very appropriate at this point), everything else is the "small stuff". Ouch, didn't intend that as a pun, but ...
Having had all nerves taken, I can understand to a degree. No wife/girlfriend here, and that said, things are problematic. I have experimented (and continue to experiment) with Trimix, which works, sometimes too well, in the quest to have something to offer when the relationships get to that point. Pity that shots don't fit into the profile of the perfect mate for some ladies.
I have read that some doctors believe that continuing the pills, and alternate use of shots, encourages nerves to regrow, if they were only cut as opposed to totally removed.
There are a number of threads on Trimix here, so you may find some useful information.
