So a follow up on my situation post circ. After my procedure I'd lost a good half of my length.
Following the advice on stretching exercises given by members on here I'm happy to report I've gained a couple of inches back. I went and saw a specialist and showed him pre-circ photos and his words, and I quote, were "Shit that's a big dick. It's too big to stay small. Be patient it'll come back."
So I guess that having it done at 48 and expecting the little guy to be fully operational in a short time is unrealistic. But at least I can have sex again now.
Big thanks to all for their support..
