I believe two people should enter a relationship as fully formed humans, therefore, anything their partner willingly gives them is a bonus. Being in a relationship "entitles" you to have the unresolved issues buried inside of you brought to the surface so you can heal them. If instead you blame your partner for showing them to you, you will end up in a miserable relationship. If, however, you take the opportunity to grow (and hopefully your partner does as well) you will have a relationship that transcends time and space.

If you enter a relationship and feel entitled to her body, her time, her domestic labor, you are only in that relationship for what you can take from her.

In short, no. There is nothing that being in a relationship entitles you to take from another person that isn't freely given.
