Can extracurricular activities help reduce teenage sexual activity?

I will argue that involvement in extracurricular
activities can help to reduce sexual activity in some teens.  Specifically, I will argue
that teens who engage in sexual activity as a way to improve their image of themselves
will be less likely to do so if they participate in
extracurriculars.

One reason for teens to have sex is low
self-image.  Some teens do not really like themselves.  They may engage in sexual
activities because they think this is the only way they will get others to like them. 
Or they may do so because it makes them feel like they are worthwhile.  If teens are
having sex for this reason, extracurriculars could help
them.

Extracurriculars can give teens a feeling of
accomplishment and belonging.  Teens can find an activity that they are good at.  This
will help them feel more worthwhile.  They can be part of a group.  This, too, will help
them feel more likeable.

In these ways, extracurriculars
can help reduce sexual activity among some teens.
