here is a piece i found
The brothers agreed upon a protocol governing their relations with Draupadi, their common wife. An important point of this agreement was that no brother would disturb the couple when another brother was alone with Draupadi; the penalty for doing so was exile for a year. Once, when the Pandavas were still ruling over a prosperous Indraprastha, a brahmin came in great agitation to Arjuna and sought his help: a pack of cattle-thieves had seized his herd, he had recourse to none but Arjuna for a remedy. Arjuna was in a dilemma: his weaponry was in the room where Draupadi and Yudhishthira were alone together, and disturbing them would incur the penalty agreed upon. Arjuna hesitated for but a moment; in his mind, coming to the aid of his subject in distress, especially a brahmin, was the [[raison d'etre]] of a prince. The prospect of exile did not deter him from fulfilling the duty of aiding the brahmin; he disturbed the conjugal couple, took up his weaponry and rode forth to subdue the cattle-thieves. Upon finishing that task, he insisted, in the teeth of opposition from his entire family, including the two people whom he had disturbed, upon going away on exile.
