Lately I've been having the urge to not want to clean and cook all the time.
Why don't you want to cook a clean more often?
I want my girlfriend to help me with cleaning and cooking.
Not everyone is a fan of cooking and cleaning and that's fine. As long as you keep the house in a clean manner that you aren't getting bugs or pests then everything is fine. Have you thought about making a game of cleaning to see if you will like that more?
I don't want my girlfriend to lose her femininity. She needs to do it for me.
Your girlfriend meaning doesn't apply to her femininity. Very misogynist to think that way. I said try to make fun of the cleaning and get your girlfriend involved and you could both have fun with it.
