Post-orgasm feeling is the same. Horniness, need to continue goes away, just as it did before implant. Yes, a sex marathon is quite possible, but you may not have the desire for it or the energy for it.

How much pleasure you get post-orgasm depends on many factors, and the implant has almost NO BEARING on any of that. It is a mechanical device and has no influence on your mental, emotional or physical state, ONLY on your penis' rigidity (of the shaft - the other tissues are not affected by the implant).
You are still the same man you were before the implant with the same cares, strengths and weaknesses you had before. The only difference is the rigidity of your penis. Of course, that durable rigidity will have an effect on your mental state.
Probably the change in your mental state will be most evident in your confidence level and your ability to concentrate on your love-making/fucking techniques and on your partner's reactions/feelings. You will not have to be concerned about cumming too soon or losing your erection. That perforce will take a load off your mind and lead to a massive reorganization of your priorities during sex. Take advantage of that freedom.
I will render an opinion for you since you asked about "marathon" sex. If your wife is into quantity (length of lovemaking session), OK. Pay attention to the clock if that pleases her. But my suggestion is to pay more attention to the small signals she gives intentionally and subconsciously as she experiences your attentions. You now have the freedom to completely ignore your erection and pay attention to WHAT YOU DO WITH IT as well as what you do with your arms, fingers, lips, voice, etc to make her experience more intense for whatever length of time you two remain in-coitus. 20 minutes of intense mulitfactorial pleasure may weill trump 2 hours of uninterrupted thrusting.
With an implant, you are free to pursue either pathway to pleasure.
