Boundaries include physical walls, time boundaries that set aside and protect the couple's time together, conversation boundaries that create limits to what one can say, and personal-space boundaries that define how one can be touched. Boundaries protect the relationship from romantic competitors and, perhaps more important, from well-meaning friends, family, and children. The paradox in this principle is that boundaries, which at first appear restrictive, actually are a means of creating more freedom and excitement in a relationship. Without the emotional safety that is provided by relationship boundaries, couples cannot relax enough to share their personal truths. Just as it is difficult to love and value a person who does not love and value himself or herself, it is difficult for parents, children, and friends to respect a love relationship that does not create its own boundaries.
Children especially have no interest in supporting their parents' intimate life.
They don't even want to know about it. Neither do friends or parents. No one cares about your sex life but you and your partner, and it is up to both of you to create the boundaries that protect your intimate moments. Sometimes a couple can spend a weekend away from the family or hire a babysitter during the day when both still have energy to pay attention to each other and to be adults alone together. Couples who cannot afford relief of this kind can go to another room and shut the door for a while or ask a friend to keep the children.
