Actually that would depend on whether these Werewolves have Human "periods" or Wolf "heats".
In the case of the latter (heats), scent and instinct will keep the couple busy, in every sense of the word.
In the case of the former (periods), Male Werewolves probably go fishing during that little troubled time.
Kris has the answer...
Frightening mental image: Butch with PMS and going into Heat. Either way, you're gonna die.
