Its the meds. Study the side effects of all of these PD drugs. Gambling is also a side effect. My mother was going to the casinos at all hours. She never gambled in her life. So strange.

from my understanding and talking with my dr yes it is normal

I was hyperactive sexually from the get go. As a gay man living in NYC SF and abroad, Brazil,Paris. It was really not a problem. I'm married to my husband and was in an open, don't ask don't tell situation. Now with PD all my outlets won't work. I'll be honest here. Many of us have sexual needs. My neurologist asked me about this part of my life. My husband goes with me to all my doctors appointments. I blushed and skipped the question. In reality I have resorted to watching porno and masturbating. I'm somewhat ashamed but I'm not hurting anyone. I have the same person for 28 years. We ceased having sex a very long time b ago. He is my caregiver, best friend and intellectual and social companion.
