Thanks so much for chiming in. We have been in contact with the psychiatrist. He was on an ant anxiety med that helped particularly with his startle effect. When the sex stuff started he had to come off that and was put on another medication. The doc said he could not take a stronger dose... the side effects would be worse than the behavior. We are planning on talking to our GP in a couple of weeks when we have an appointment. Seems to me there has to be something that would help us.
