Though I'm polyamorous, I don't always have multiple partners. I've also avoided talking about my partner(s) here. It just seems...weird.
My current partner and I live together for almost a year. The place is small, and perfect for one. With two, it is crowded. I've also got two cats, and my partner is a dog person. Awkward.
But part of poly is enjoying the differences, and learning about other people. My partner is starting to like the cats. (but still wants a dog). Ultimately, I see us moving to a larger place. We've worked through the six month contract, have goals as individuals and as a couple.
Currently, I'm facing some health problems, and have been thinking about how having multiple partners can be wonderful in this situation. About two years ago an acquaintance was battling breast cancer, and had both her husband and boyfriend for support. I watched at a distance, awed at the situation.
