Well I am 60 and 36 years post-op so I guess things have settled as much as they ever will.
When aroused, I do lubricate, some from the urethra and some (less) vaginal but with sufficient foreplay, intercourse is no problem. At orgasm, lubrication is "generous" but I could not say where from (my mind is elsewhere

)
One advantage of post-op evolution (over GG's) seems to be a much greater sensitivity over the full depth of the vagina.
