Obviously, you are having trouble coping with your desire to boink her, so I'll use smaller words.
She is not an adult.
You are her father. This means that legally, she is still your responsibility until she is 18.
This means, that adovacting, that means "sticking up for", her Rights is your responsibility.
This also means that legally, you can be held criminally responsible for the consequences of her actions.
Yes, she is old enough to engage in sex. But, you are her legal guardian until she is 18. This would be like an Army Sargent ordering a Private to blow him. Bad mojo.
Got it? Or do we just have to assume you are completely mentally deficient?
Not in my state. No parent can control the actions of their child after they are 16. We are legally responsible for the effects of their actions but we cannot excersize control over them. That is the law.
So, your flat out wrong. She is at the age of consent. If she wants to give Clinton blow jobs there isn't a damn think I can do about it. If we desire to have sex in the privacy of our own home then their should not be a damn thing the state could say about it.
