I wouldn't like it in that situation, no. If you aren't together and are doing other people but not each other what exactly is your relationship?

The only way I think it really works is if you are so hot together it pulls other people in, and if you are both wired to be turned on by hearing about the sex with other people, and have extremely good communication, like to the point it would annoy most people. It can't be to fill a hole (ha ha) in the relationship you have. It can be good if you are both enthusiastic about it for sure. I don't personally know anyone who has successfully used it one sided to manage a libido difference, though the top comment here is a guy saying he does that.
