I'm definitely better at switching in poly than I am at switching in BDSM... I tend to be very bottom-y, and though I really get off as a top, I really have to psych myself up for it and get myself in the mood. It's fun though.
I'm relatively certain we'll stay poly for the rest of our relationship. Mainly because once you open that cork, it's really hard to put the genie back in the bottle. If it was my husband's request, that would be a different thing, but it wouldn't be fair for me to "turn it on and off" at my convenience. What's good for the goose is good for the gander.
