The nature of blood relationships is such that consent cannot be presumed.

What the hell is that supposed to mean?

It's similar to statutory rape, where a child is presumed to be too young to give consent. Blood relationships create psychological bonds and pressures (in most cases) by which consent for sexual intercourse cannot be assumed to have been obtained.

With all due respect, that's a lot of crap. If that were the case, then blood relatives should not be permitted to enter into any kind of contracts with each other. To wit:

You can't serve as the executor of your father's estate, you can't serve as the witness at your brother's wedding, you can't co-sign a car loan for your child, or serve as a co-owner of a piece of property with anyone in your immediate family, etc.

You've got to be kidding me.
