Avery Wake up, this is a completely different culture. We have at least one person here that is over 30 and has been locked up by parents for more than ten years. Do you want to editorialize on that? I'll bet they have a happy life.

Yes, it is another culture. Nevertheless if you do something do it right.
From @ZeynepFox posting her future husband will lead their relation including sometime spanking for her for her development.
They live in Germany and they respect and following the German law.
As an adult you make your own decision and nobody has the right to do so for you without your consent.
If, as a young adult, you are aware that you do not know everything and that you also have less experience, this shows maturity. Therefore, when it comes to important questions, it is good to get opinions and advice from others who know more or have more experience. One way is to ask your parents. In the end, however, you decide for yourself and stand by it.

If her mother-in-law insist to have the key at her wedding and to keep it against his will than he shows he is not the leader of his own family. Apart from that, it is against the law to use $240 StGB (coercion).

If he agrees than his mother should ask herself what she did wrong with her education of her son that he is not able to fulfil his duty or can't handle his wife.

      Joh and to keep it against his will

      If I understand right, it's not against his will

      • Joh replied to this.

          Laura If I understand right, it's not against his will

          ZeynepFox his mother may want to observe and supervise the amount of sex we have

          I can't find any information that he agree to it either.

                Joh He agrees to let his mother hold his bride's keys. Why it should be different?

                • Joh replied to this.

                    Joh Because they are not married.

                    If he is mature and responsible he will not have sex with her before marriage.
                    I can understand if her parents require her to wear a chastity belt.
                    But in this particular case his mother requires it, that means she doesn't trust him

                        Laura It's probably forbidden

                        I don't know, I guess I could have it done if I really wanted to, but there is no medical necessity from my point of view.

                        Christine Don't give parents such a crazy idea.

                        i didn't do that. it's more about when, for example, german women want to have a "virginity certificate", in my opinion the parents are left out.

                              Laura But in this particular case his mother requires it, that means she doesn't trust him

                              This is one way to see it.
                              Another way is she doesn't trust her or she will be sure nothing can happen like rape.

                                  Joh she will be sure nothing can happen like rape.

                                  Can she rape him? 🤣

                                  • Joh replied to this.

                                      Laura Yes, it is possible. It's not often but already done.
                                      But she herself could also be raped by someone before she is married.

                                          Angelina but after the wedding, no one but the two of you will be interested

                                          Both could be interested if explained the advantage.

                                          Angelina sex life is something very special and intimate

                                          That's exactly the reason, and they should wait at least until night.

                                          Laura But in this particular case his mother requires it, that means she doesn't trust him

                                          No, it's because her parents are irresponsible. She will have to present that certificate right before marriage as a proof she didn't sleep with him yet. Otherwise it would be the shame for both families and other negative consequences.

                                          Joh Another way is she doesn't trust her or she will be sure nothing can happen like rape.

                                          Not rape, but seduction.

                                                    HHelen No, it's because her parents are irresponsible.

                                                    And just how did you arrive at that conclusion?

                                                        Avery And just how did you arrive at that conclusion?

                                                        Because they had to take care about their daughter's virginity, rather than his parents.

                                                            Joh But she herself could also be raped by someone before she is married.

                                                            Less likely

                                                            HHelen No, it's because her parents are irresponsible.

                                                            Or they trust her more

                                                                HHelen Because they had to take care about their daughter's virginity

                                                                I guess they did a good job, she's still a virgin.

                                                                    HHelen Both could be interested if explained the advantage.

                                                                    HHelen That's exactly the reason, and they should wait at least until night.

                                                                          Avery I guess they did a good job, she's still a virgin.

                                                                          It's more about the religion. And she is still young.

                                                                          Angelina i see no advantage in this

                                                                                HHelen It's more about the religion. And she is still young.

Like buying a horse. I'd say it's business, Sonny, it's not personal but I doubt you've seen the Godfather.

                                                                                    Angelina it's more about when, for example, german women want to have a "virginity certificate", in my opinion the parents are left out.

                                                                                        Avery Like buying a horse

                                                                                        Avery but I doubt you've seen the Godfather
