Why does my boss act like this towards me?

My supervisor at work is a married woman in her 40’s. On a weekly basis she comes in the morning and touches my face and asks me if her hands are cold. She then uses my computer to log in and bends over in front of me. She makes subtle jokes about her husband doesn’t “take care of her at home” and says she needs a young man who is a specific age ( name the number which is my age) and looks at me and starts chuckling. She mentions from time to time to me about how other women in the office mention in small talk about how attractive I am without me asking or bringing up that subject. She doesn’t act like this with other co workers, what going on? I have never made an advances toward her.
