The simple answer is, this is entirely dependent on the boundaries and limitations of your partner.
If she says no, that's what she means. Don't force her to do things she isn't comfortable with.
If you decided to anyways, then you obviously have no respect for her, or women in general, and could be subject to criminal charges if you force her.

The're should be nothing too hard, difficult or dirty for you to do for the woman you love, married and committed you life and being to for as long as such thing is legal and wouldn't put you or your family in danger. The moment you decide to get married to some, that some becomes same as you and you should be willing to do anything to make such a someone better.
If the person is just a girl friend, then you don't owe her much but if the person is your married partner, nothing should be too big or too small to give to the one that you've a made a life time commitment to love
