My 86 year old husband with PD has been declining for a number of years (I am 20 years younger and have MS). We moved him into an assisted living facility in February as he needs assistance with all activities of daily living. I spend every evening with him from 4 pm to 9 pm. We are very close but he is now incontinent and has Parkinson's dementia. He still seeks sexual intimacy with me. I'm no longer emotionally able to accommodate him. Although I demonstrate a great deal of closeness and physical affection toward him with lots of hugging, hand holding, stroking his face, etc., he is very resentful of my reluctance to engage with him sexually. I don't know how to explain to him that it's now unappealing to me. Any advice would be greatly appreciated.
