Age Gap?

Hello,

Had to use a new account because my family knows my old one. I'm (27 m) and she's about to turn 22. Is this gap too big? We have been together for almost a year. I really like her but I don't want to do anything to hurt her. I keep seeing things on reddit about age gap and I'm worried I am hurting her. I know I got alot of growing up to do at my age, and tho our relationship has gone great so far, I dont want to hurt her at all. Is this gap wrong?
