Actually, a broader view of this seems useful. Any time we say “I am an X”, the person you’re talking to is likely to take it as you implying that they’re not an X, unless they already identify as being an X as well. So any good-sounding X will come off as insulting. A bad-sounding but interesting X might be useful, but that seems prone to backfiring, and neutral values of X are both difficult to construct and not very stable.
Stating it as ‘I do X’ or even ‘I do X well’ seems more likely to be taken well—there’s less of an intrinsic implication about whether the other person does X.
