Brain tumors could: Cause all kinds of strange behaviors. It depends upon where in the brain the tumor is growing. If it is near the part of the brain that impacts on sexuality, it could occur. If you are concerned that you or someone you know has a brain tumor, consult with a physician.

Yes: Brain tumors can cause many disturbances of behavior including a form of hypersexuality called the "kluver-bucy syndrome". Patients with this syndrome may seek sexual contact with both men and women, and tend to use their mouths to evaluate any new thing in their environment. Usually these patients have disease, whether infection or tumor, in both temporal lobes.
