on the desire to expose oneself in words

I have a predecessor! (I appeal to the inflection in those translated words of Nietzsche's in commentary on Spinoza)

"The sordid details of his orgies stank under his very nostrils: the sootcoated packet of pictures which he had hidden in the flue of the fireplace and in the presence of whose shameless or bashful wantonness he lay for hours sinning in thought and deed: his monstrous dreams, peopled by apelike creatures and by harlots with gleaming jewel eyes: the foul long letters he had written in the joy of guilt confession and carried secretly for days and days only to throw them under cover of night among the grass in the corner of a field or beneath some hingeless door or in some niche in the hedges where a girl might come upon them as she walked by and read them secretly."

James Joyce, Portrait of an Artist as a Young Man (III:488-499)
