Consent is a fundamental aspect of any relationship, whether monogamous or non-monogamous. However, different types of relationships may present specific challenges to obtaining and maintaining consent. In monogamous relationships, based on the assumption that two partners are exclusive and faithful to each other, clarity and open communication about desires, boundaries and agreements are crucial to ensuring consent. It refers to mutual agreement and respect for the partner's wishes regarding intimacy and sexual interactions. However, this assumption may not always be clear or agreed upon by both parties. In non-monogamous relationships operating on the premise that one or both partners may have multiple romantic or sexual relationships with other people, consent becomes even more complex because it involves multiple people and varied dynamics. Open communication is essential to clarify and reinforce the agreements and wishes of all parties involved. Respect for the boundaries and needs of each individual becomes fundamental in ensuring consent in such relationships. Regardless of the type of relationship, consent requires transparency, mutual respect, and clear and explicit agreement between all involved. It is an ongoing process that requires open and honest communication to ensure mutual understanding and respect.
