Age Just A Number##

I knew I have always been into older guys. never dated anyone close to my age, my baby daddy is 5 years older than me. we've been broken up for about 3 years. I currently started dating someone😊 I do not know his exact age but I know for sure he's gotta be at least 10-13 years older than me. i am 24 . we both don't care as we don't even bother touching the subject about our age. I just know everyone gets surprised when we go out and hold hands or kiss in public, because he obviously looks a lot older than I. Is it really that "wrong" having that much in age difference?
