I dunno if this can be described as deep feelings but I clearly felt limerence ("falling in love") for girls of all the ages (from my age up to 20 years more old) since when I was 5. In fact I can't even say much has changed in me since then besides emotional (and, obviously, analytical too) intelligence growth and experience accumulation. I don't feel anything I couldn't feel when I was 5, I just understand the things more and know better what to do.
