Definition - What does Time Limit mean?
A time limit is a predefined number of hours or minutes in which a BDSM scene is to take place. In the BDSM community, it is common to set a time limit on how long a BDSM scene will take. The time limit is agreed upon by participants before the scene begins, along with participants' hard and soft limits.
Kinkly explains Time Limit
Time limits are most common in casual play between participants who don't know each other. Like other types of BDSM limits, this one ensures that participants are safe and remain in control of their situations. Between long-term couples who practice BDSM, time limits can be used for certain phases of the relationship, such as training.
