The question did say "your" significant other - the "you" in "your" implying the person writing the response to the post, right? No one answering has to jump to any conclusions as to the nature of the relationship, they're IN the relationship so we hope they would know the framework of it...lol

In my case, there are people J and I know and have discussed that we would be open to playing with. That has happened, and it was fun. A stranger invited to screw me, on the other hand, would be a SERIOUS NO GO. I would frankly question if J had fallen and cracked his skull on the way back to the house. I don't sleep with people I don't know and that I don't have trust, friendship, and a bond with and I don't plan on starting.
