Do you age up yor F/O over time or keep their canon age?

I've been thinking about this for a while and wanted to hear how other people handle it.

For example, if your F/O is canonically 19 years old, but you yourself keep getting older every year, do you mentally age them up with you? Or do you keep them at their original canon age forever?

One reason I'm asking is because there's a lot of social pressure and judgment around legal age gaps, even when it comes to fictional characters/anime characters. Like, society might see a 30-year-old loving a 19-year-old fictional character as weird or questionable, even though the character obviously doesn't physically age over time.

Right now I'm 22, so it doesn't feel strange to me, but I sometimes wonder how other people deal with this as they grow older while their F/O stays the same age canonically.

Do you:

- age them up together with you?

- reinterpret their age over time?

- or handle it another way?
