Last year, my vee was very new at Valentine's Day. I mailed them both cards (because that's what I do) ~ one lives a few hours away and the other lives next door. My men love each other very much, and would never consider being in a bed together. Unless maybe they were camping and were both at the bottom of two bottles of vodka and they happened to pass out next to each other. But probably not even then.
I was with both of them for Christmas Eve at CBF's mom's house. It was quite an event, for ME. No one else seemed to notice.
So, I agree with those above me. No need to be superhinge. Talk to both of them about what you would like. If you don't know, talk to them about what they might like.
