That is all up to you, fluff is nice, just don't make it super in your face bring it up all the time fluff. Give you a example, I have a friend who made his character the "ladykiller" of the campaign and would in character use it as a insult to the paladin every time he would woo a female npc. Eventually the paladin got sick of this clapped him in irons and left him rotting in the town jail, thus ended the worst rouge I have ever seen
