Boundaries explain an individual’s limits about which sexual activities they feel comfortable taking part in. Boundaries imply a set of personal guidelines put in place to protect an individual from events or situations which may cause them to experience mental, physical, or emotional harm or distress. Each individual will have a different set of boundaries based on their unique preferences, tastes, and past experiences.
Sometimes boundaries are clearly defined and negotiated before a couple engages in sexual activity, such as in a BDSM relationship, but often boundaries are discovered more gradually as a couple gets to know one another.
