OK, I guess that wasn't all.
What if I just simply told my attraction that "Guess, what? I was feeling a little hesitant about all our cuddling and spending time together because I wasn't sure about how DF would feel about it, and I talked to him, and he's actually perfectly fine with it!" Without a whole schpiel about polyamory and relationships and stuff... I mean, depending on how he reacted to that, it could come up anyway, but maybe I don't have to bring it up? Or am I just trying to avoid Real Discussions? Gah. I don't know. More thinking.
