Males and females also often control how they are perceived in terms of masculinity or femininity. Boys and men might sometimes make their voices sound deeper or speak in short sentences to reflect an old stereotype that males are unfeeling and unconcerned with self-expression. Females on the other hand might feel the need to speak in line with the speech patterns of their peers, and this may include tacking on culturally specific phrases like "or whatever" and "that's hot/cute" to indicate they identify with the female gender and traditional interests. These of course are very simple ideas about what it means to be a man or woman. In contemporary life the border between male and female is sometimes becoming less strict. In Western societies psychologists support that people who show alternative gender expression are still medically normal.
