is this a an age gap

I think technically? They're both adults and I don't remember if the age difference is anything significant (but I don't think it is)
The only thing that's really emphasized is that the top is younger and the bottom doesn't usually go for younger guys

The top is 23
& I tried to find the bottom's age but idk if it's ever stated
But it's kind of implied that he's mid to late 20's
