my child has sexually behaviors problem

MY CHILD IS A 13 YEAR OLD BOY AND HE BEEN MASTUBATING EVERY DAY AND HE ALSO TEARING HIS UNDERWEAR TO PUT HIS FINGER UP HIS RECTUM.  HE ALSO IN THE PAST HAD SEXURAL BEHAVIOR WITH ANIMALS. I'M AT MY WITS END WITH THIS. IS THIS NORMAL FOR A BOY TO DO THIS?  HE ALSO ON MEDICATION  DEPAKOTE   RISPERDAL AND GUANFACINE AND I WAS WONDERING IF HIS MEDICATION IS CAUSEING HIM TO HAVE SEXUAL BEHAVIORS LIKE THIS.

It's unlikely that the medication is fueling this behavior, and the behavior is not normal for a child of any age. Inferring from the medications you named, your son has been diagnosed with bipolar disorder, and hypersexualized behavior is not uncommon in adolescents with this condition. Your brief description indicates that he might display paraphilias, and this issue should be addressed with his clinicians.
