It’s important to remember she likes you for who you are.
If you’re dating her, you must love something about the way she looks. Now, if someone comments on how great she looks for her age, you can whole-heartedly agree!
The best thing you can do for her is help her embrace it and take as much joy as possible in the changes her body is going through. You love her eyes (those never really get older), and her wrinkles, and the way she does her hair.
Even if she’s taken great care of her skin, she’s still showing signs of age.
She should love herself and the skin she’s in, and you can help.
If you’re dating a cougar, it’s important to know that her age and experience has taught her a trick or two in the bedroom and she knows what she likes and what she doesn’t.
