How much does age difference matter to you for romantic relationships?

Do you have a limit of a certain number of years in either direction that you set yourself? Does it depend on the maturity level of the person, or the connection you feel with them?

I remember just a few years ago, realizing that all of a sudden, for me, age didn’t matter so much. I’d always been with people older than me, but since that realization, well, I’ve been with people more than a little bit older than me haha. Makes sense to me; I had to grow up fast and I often have trouble relating to people closer to my own age (in a platonic or romantic way).
