This is so common regardless of Parkinson’s. The common theme is a lady of a certain age starts to experience the effects of Menopause. Their world is thrown into turmoil and a common result is Men on Pause.
The Menopause has many different effects and treatments, some of which have potentially life threatening side effects. With or without meds Women are left feeling uncomfortable through hot flushes and pain during sex due to dryness. These are just two common effects. There are many others that impact on their mood and self esteem. Ask your wife about how the Menopause affects them.
Now add in their partner being diagnosed with Parkinson’s. It hardly surprising that many wives see the whole situation as their cue to do what they know and see the carer role as a nurture role, and that excludes sex for them and you as a result.
So in the early days of earlier onset Parkinson’s your mobility is less of an issue and the meds can make you feel almost normal. These meds tend to be dopamine or dopamine agonists, both of which have side effects that make you less in control of your inhibited desires. These desires may be sex, spending, gambling, hobby related.
You need to recognise what desire has become more uninhibited for you and talk to your doctor, and partner about how to keep track of things and how your meds can be altered.
There’s so much more I could add. Start with your doctor and the meds review. Then discuss with your wife how you still desire her and go carefully and slowly from there.
