Spot on, as always, my dear friend. I could have highlighted the entire piece.
Personally, I've recently encountered the phenomenon you described in your previous relationship. Just our talking about what we desire has changed everything for the better.
There may come a day we act on it, but for now, just being open about it has made all the difference.
I also posit, these conversations need to be open, honest, and vulnerable. I can't express enough how important it is for each partner to say what's truly on their mind. I've been in situations where, I found out later, my partner agreed with what I was saying (about possibly opening things up etc) because they thought that was their only option. I've been guilty of doing that myself in the past.
That does nothing but make things worse.
Thank you again.
