Great news for you and your partner Gregory. If it can happen once it can happen again, and again!
With regard to recovery as a % measured against what any man had before, there is no set answer, it varies from man to man and also with occasion and the circumstances.
Sometimes it will be less than before and then sometimes it will be amazing, just like before the op. Just hope that when it is amazing you have the right company and can use it!
