Hi Kell
I've just had a NSM (left breast) on 10 Feb and I'm very happy with the result, psychologically I think this is a better option if it is possible for your circumstances. You have surgery and wake up with a new boob that looks similar so the shock factor isn't as bad.
I still have nipple sensitivity not the same as before surgery but improving slowly.
If you can keep the nipple I would try but in the end it comes down to your choice and the risks involved. It's good that you have the time to research your options you need to be confident with your decision.
All the best.
