I don't have any technical solutions to the threesome bedsharing question, but I can't help wondering whether the two boyfriends are also involved with one another in a loving / intimate relationship -- and of what kind, and how much they are cuddle-friendly with one another(!).
What is the largest bed size available on the market? Can you lay out multiple futons on the floor, side-by-side? Maybe layered several?
oh... wait, all three of you are male! that makes things altogether different from my initial imaginings... so many people to know ... forgetting details ... I think I've seen you three somewhere before! here online, that is.... but a busy life makes for hard remembering. No pun intended!
Okay, now I'm envious!
I want two boyfriends, too!
