I agree with everything about graham fetishes, but I think when it comes to old gramon, graham is more soft with damon
i do think that old graham/young damon dynamics is all about how much graham values youth and how damon embodies it – knowing graham spent a better part of his young years trapped inside his own insecurities makes it clear as to why he cherishes damon's boyish manners. he adores damon and, at the same time, he sees and reckons his very immature ways, immediately noticing it as it is: the type of foolishness that only comes with age. i feel like old graham very much sees how much of a facade damon puts on (something that himself wouldn't see until a much older age in his life), and, contrary to young graham, he doesn't envy nor resents damon's necessity to "adapt to survive" (like circa 1994, when he doubled down on the "laddish behavior" once the gallaghers came into the scene), but sees it as young disposition; he can't blame him for that, can he? so i feel like old graham would be totally mesmerized and, yeah, have a soft spot for young damon, the same way old damon would have for young graham
now if we're talking about them both being older, as of it today, i do believe sex is something fairly more romantic than it was when they were younger. not in a softer way, but in the way that their feelings for each other are much more in the open, they don't have much left unsaid (which built tension around their young years. i can still see them high in adrenaline and making it into the backstage for a quickie but tbh older damon just isn't much of a sexual person (he wasn't it even during his younger years), so it all comes down to the intimacy sex has always brought into their relationship
