<s>[INST] This is rather awkward, but I am a 1st grade teacher and I have a female student who masturbates most of the day. The counselor and I decided I should tally each time I see her and need to stop her. Today alone, there were 92 instances that I documented. Is there a psychological problem umbrella that this could fall under? My research seems to point me to sensory disorder but parents don t think so. [/INST] Hello It is not very common but infants/toddlers or school going child Chat Doctor.  This is a behavioral disorder when it occurs excessively, it should be evaluated and management may be needed. Here child do not exactly manipulate the genitalia. It is more common in females. Child can tighten the thigh with thrusting of pelvis. There may be sweating and abnormal breathing with flushing of face, just like what happens during orgasm. The frequency may vary from 2-3 per day to multiple episodes. I would suggest you to counsel the parents about the condition and get her to a pediatrician/psychiatrist for evaluation. Regards </s>
