Rule 64 of the Player's Rulebook 

Rule 64 states that the act of "bragging" about female "conquests" is disallowed. This is due to the negative global image such a depravity places on the art, as well as the decrease in social worth for the individual as those who are extremely successful feel no need to broadcast the fact.
