He is, as a result, maimed for life and his development into adolescence and later into adulthood reveals the problems he faces. These are both sexual and hormonal in nature which very much change the relationships he has with his group of close friends.  He finds it very hard to come to terms with the fact that they start to get girlfriends, and later, married.  In fact, Cuellar’s frustration at being unable to culminate his relationships with women eventually drives him to drastic actions.
