The menopause issue has been well covered here, so I will only say this - just because a woman isn’t using those ‘parts’ anymore doesn’t mean that you don’t have to take care of them.
I learned this the hard way.
So, now I use estrogen cream twice a week and coconut oil on
other days.
After two episodes of pelvic floor PT, I learned to continue the PT at home. Pelvic floor PT can feel tedious. The same results can be achieved by just having sex. With a partner or with yourself. Increased blood flow to area.
