Know this sounds like a cliche, but every woman is different.
My mother and aunt both had difficult lives around periods, both eventually had hysterectomies so I was dreading reaching that part of my life. Am not bragging in any way, but after a few heavy periods, everything stopped. Had a couple of uterine polyps but nothing serious.
Yes, my sleep pattern has changed. My hair is thinner. Trying hard to follow a nutritional diet. Losing weight has always been difficult. Don't mention the facial hair!
As for sex. Would love a passionate night (or two!) because, how can I put this, the desire is greater than before. A couple of "purchases" have helped but there's nothing like human contact!
