Yes, it could be daddy issues indeed. It is normal for a girl to have a crush on boys that are a little bit older but older than thirty-five? No, that is not normal. I remember I had a crush on a boy two years older than myself when I was in Elementary. I had my period at 9, and I also matured real quick, but I still had a crush on boys that are close to my age. I only started liking older people like my professors when I was in college. But that was because I found most men my age to be boring and uninteresting.
