We need to neuter the guys in the friend group immediately. The boys in the friend group should not be allowed to have kids. Their offspring will lead to the end of the world. This will also lower their testosterone, benefiting them so they (hopefully) aren't horny teenagers anymore. According to studies at Brown University, "neutering decreases the chances of developing prostatic disease and hernias, and eliminates the chances of developing testicular cancer. It also reduces problems with territorial and sexual aggression, inappropriate urination [spraying] and other undesirable male behaviors" (www.brown.edu) These are big issues with our friend group, but there's an easy fix: neutering! Neuter your local boys today!
