I stumbled on this video about a year or so ago, and it helped heighten my awareness and intention setting around considering new sexual partners. Not all of my partners are in complete alignment with my intentions, but they don't need to be! ;-) Being able to identify and talk about our intentions can help set appropriate boundaries for all involved, and prevent assumptions, expectations and projections from creating unnecessary conflicts.
What does sex mean for you? How might that meaning change in different contexts? How do you think this conversation might change the quality of the sex shared if it was part of each encounter, including with known partners (since intentions and needs might change day to day)?
