Like anything else, it depends on the manner by which you go about things. Some people are excellent at being "showy" in a totally nonchalant manner, which I don't mind, and in some cases, admire. For every degree there-after that the act becomes more and more transparent, and it just seems like attention-getting desperation to me.
And I am not exactly sure how you could be an exhibitionist, like say, a streaker, and do it in a coy fashion, lol!
