had to sit on this message and ponder it like an ancient scholar with philosophy. much to consider! i think geta would be willing to bottom for caracalla if caracalla really desired it - i don't think he'd deny his brother much of anything, really, aside from things that would cause him & them harm. so the better question is if caracalla would want to top, and i think the answer is he might! he seems to be guided by his whims, and if the whim struck, i could see him asking to top for a change. geta might be a little unsure at first bc it's a change from their usual, but caracalla is bratty and demanding, and i think geta would acquiesce.

now, would caracalla be any good at it? debatable. would he tire out quickly and make geta take over? most likely. muscle weakness & poor muscle control are symptoms of advanced syphilis, so idk if he'd have the energy to go at it very long. so either geta is going for a ride (which i can see), or they're switching places pretty fast lol.

tl;dr yes, but it's probably not their usual dynamic
