This article is about the pressure to do “it”.  All of this girl’s friends are not virgins anymore.  She is the only one left in the group of friends that is still a virgin.  All her friends strut around like they are all hot stuff since they have lost their V-cards.  The writer states that the people that are behind on all the “mature stuff” are starting to feel the pressure of others.  Her friends had changed the way she looked at guys; she would ask herself if that guy was the one.  She wants to wait and have sex with a connection.  Time matures you, not sex.
