Is it selfish to ask for a back and feet rub?

Cynthia
I'm a stay at home mom. I clean and cook and take my daughter to school I feel like I'm up all day . So even though I don't have a job I feel like I work to and at the end of the night my feet hurt and my back... I want to ask him to rub me but then I dont want to bother since he works hard everyday... What do you lady's think ?
