Re: wife likes the fantasy, but nothing more, how to proceed

Her argument are:
She is very satisfied with our sex life. And even I last short she loves the penetration.
-Good is often the enemy of great. Said another way, why settle for ‘satisfied’? Is this phase not about potential?
She has had numerous sexual encounters before me and she says it was fun and exciting but not comparable with the good sex we have.
-previous encounters lacked a bond or connection and were not satisfying; fix that by encouraging she get to know (date) any potential bed-mate
She appreciates my efforts to work around my quick ejaculations.
-nice way of saying it sucks that you can’t fuck me properly, but I’ve gotten used to it
And finally she beliefs that the practice will be less fun than the fantasy, she thinks this will be a disappointment.
-disappointment along the way is a possibility as nothing worth anything ever comes easily
