Like Numex, we found it easier to arrange solo dates than together dates. As we progressed and embraced the idea of having long term play partners, we recognized that going on play dates together was going to become harder to do with long term partners. We discussed that long term partners would sometimes have sexual needs that wouldn't want to wait days to respond to. It would need to be more spontaneous, like "Hey can you come over?" A response of "Sure, but it'll be a couple of days while we sort out a baby sitter". Kinda kills the mood
With the two long term boyfriends my wife has had, she had far more solo dates with them than both of us going. I always enjoyed her telling me the whole story when she got home, and having sex while she told me all about her date.
Now, solo dates with someone the first time....that's a different story.
