As long as you are always honest with each other you'll work something out.
If there are disappointments then there is always next time, or something else to try.
Never give up, but don't beat yourself up over it either if it all takes longer than you hope.
You're wife understands, most of us do I'm sure, because we want to help our other halves in any way we can.
I'm sure you are both very patient with each other, but for you - just give your body time to adjust.
