I won't even attempt to provide information on current EU regulation, but I give you the fundamental protection we have in the US- the 4th amendment.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
I could go into a lot of depth with that one, but won't. Instead, I will give you the more interesting Griswold v. Connecticut, 1965.
The Supreme Court held that the Comstock laws from 1870 (and still technically on the books today) that prohibited (among many other things) condoms from being sold to married couples violated the "right to marital privacy", establishing the basis for the right to privacy with respect to intimate practices. Theoretically, this could also apply to chastity belt families.
I will also relay a personal story for counterpoint- I was one day discussing that case with an accountant who does taxes for the Russian mafia. When they covered it in law school and got to the point where the decision read "specific guarantees in the Bill of Rights have penumbras, formed by emanations from those guarantees" he asked "what else is hiding in the Constitutions underskirts?" I was amused.
