Do you want to be endearing, Fuzzy, "lovable especially in a childlike or naive way"? You're certainly lovable but I was reminded me of when I was an older teen and my stepmother would make fun of me and tell me I was "kind of big for six" meaning she thought I'd done something childish. Maybe your T meant it as a good thing that you're not endearing? It's not the same as saying you aren't lovable.
