I'm 23 and she's 19?

I'm 23, she's 19. we both know each other well and come from slightly conservative families (I say this meaning both of our families are very present in our lives). My question is, is this age gap too much at our ages? Does me knowing her for a while change the dynamics of this age gap? I would really appreciate any help from you guys.
