What does Julia do during her free time

Julia has begun spending her free time, when she can, with Winston.  However, before this she spent her free time with anyone who would spend "sexual" time with her.  She lives in the moment, relishes the gifts that can come from those people who enjoy her charms, and does not seem to be as enchanted with Winston as he is with her.  In all, she uses her free time to satisfy her own pleasures and desires and does little else other than her job in the Ministry of Truth.
