Observation, at age 21:

When making medical appointments with the Student Health Clinic on campus, it is generally assumed that you are sexually active.  However, when making such appointments with an off-campus medical center (such as Kaiser Permanente, for example), it is generally assumed that you aren't.

A sign of the times?

Last quarter in my Human Sexuality class, we learned that: 

• The average age people lose their virginity at is seventeen.
• The average age people get married at is 27.
