Any ideas about what is going on and how to deal with my husband's physical hallucinations?

My spouse is experiencing increased libido secondary to his ropinirole. He would have sex twice a day every day, if I agreed. He has stopped waking me up at night, but some times there is prolong "fore play". When I call a time out, after a few days he will wake me up and ask me if I feel the bed vibrating. When I say no, he accuses me of masturbating and my sweet gentle man becomes irate and accuses me of lying sandstorms out of the bedroom.
