Just thought I'd throw my two cents in about polyamory...
My brother describes himself as polyamorous. He has a primary girlfriend that he's committed to, and, as I understand it, they periodically invite others into sexual interactions. They have rules to help make it work: 1) They're completely honest about any extra-sexual relationships, 2) They introduce each other to anyone else they have sexual interaction with, and 3) They will never leave each other for someone with whom they have had one of these interactions with. Obviously, this requires a lot of honesty and trust on both their parts, but they seem to make it work.
Personally, I don't think I could do it, (I don't like to share)
but I have a lot of respect for anyone who can make it work.
EDIT: As for today's strip, all I will say is I wish
I had a complete armour set.
