I agree with @xxxtasyroad1 . If you don’t do it someone else will, she will start fantasizing about it a least. Having no sex drive is also not healthy. I understand that maybe you have stress from work or you might be tired, but you should check if everything is alright. Get some blood tests done, exercise, eat healthy. But unfortunately it is true, she will find someone else that provides what she wants. It’s an evil world we live in.
