The issue you're facing is that you aren’t entirely understanding how we will exist in eternity. Paul writes of how we will be fixed to live properly in eternity, without struggling through an issue of mundanity to existence, in the First Epistle to the Corinthians, where he writes:
>So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable. It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power. It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body. Thus it is written, “The first man Adam became a living being”; the last Adam became a life-giving spirit. - First Epistle to the Corinthians, Chapter 15, Verses 42-45
It'd be best to read the whole chapter with great attention to each of its words just so that you can comprehend all of what Paul is saying here a bit better, but to summarize it for you, our bodies will be perfect to how God wills them in heaven. Since God's will is perfect, we will experience perfection. Because of this, when in heaven, our capacity to find joy in the things we experience throughout eternity will be ever-expanding, for our resurrected, spiritual body will be everlasting, and so too all of its feelings (now also made perfect, so no suffering will be felt) must also last forever, including joy, which, by being everlasting, must then be ever-expanding to last forever, for if it was not, then it would have a limit to eventually be reached from the time of eternity. Because God is infinite, He will never run out of ways to love us and bless us with intrigue and fascination while we are with Him for eternity. In doing this, then, our ever-expanding capability to enjoy will be binded together with His forever-ongoing capability to gift us joy, and even from this relationship, by us being permanently satisfied with God, then we are also glorifying Him in permanence, and so the perfection of eternity fulfills the eternal God and the resurrected man, and we will all be satisfied forever by being with God.
