I'd like someone to take care of me sometimes
That's reasonable. But why do you need someone?
I think it is the proper thing for a woman to take care of a man and vice versa
People sometimes want companionship and people to love them and care for them and that is okay. It is normal to want that connection with others and is expected of people.
I want a full on care. Like someone to wipe my bottom.
If you are able to wipe your bottom, I feel like you're trying to seem helpless even if you're not, and for someone that you can hire to take care of you, that may be a very challenging task that you are exposing them, even if they don't have to. If you are disabled or very old, then it is okay to get help like wiping your bottom, but if you are not disabled nor a senior citizen, then it is not.
