I have a question about Question #7. Which gender dynamics are you asking about? Are you asking from a purely money management stand-point? And, comparing to "those" in mono relationships- I'm not sure that's answerable. Mono relationships can run the gamut in gender dynamics as well, in a M/F couple or a same-sex couple. I could answer your question that yes, my gender dynamics with MC and TGIB are the same as if I were in a mono relationship with each of them, but I couldn't tell you how those gender dynamics would compare to other mono couples.
I can work on answering the other questions, but I need some guidance for #7, thanks!
