Sexual Harrasment

So,their is a lesbian at my work who is always flirting with me.She says inappropriate things like "your butt looks good in those pants" and one time she poked my boobs after asking if I had implants.Im very polite with her and tell things like "uh you shouldn't do or say that". I'd like to consider us friends so I stay polite with her. I feel like if this was a guy it would be completely inappropriate and I would report him,friend or not! Because she is a girl I'm not sure how to go about it. Lately I try my best to avoid her because I know she is going to flirt with me. She knows I'm married and 100% straight but she just won't stop. What would u all do?
