So, we started the discussion this past weekend and T is fine with the idea of the three of us going for the fluid bonding situation. (We're a closed loop, btw.)
E wrinkled his nose a bit when he heard that he'd have to go for a doctor's workup just to make sure we're all clean.
T and I talked about the "worst case" scenario (pregnancy) and agreed to talk more about that before we make the switch from condoms to no-doms. That'll be a chat I have with E, too, before the three of us sit down together on that topic.
And rudeness? Well, we try to be fair among the three of us, hence my concerns about rudeness. There are no demands being made for "access" or anything like that. Just a genuine desire to have one less step during, cough, sexy time.
