Shit post answer: I would love to have a harem of sexy men that would pamper me everyday all day, and walk around in sexy outfits.
Real answer: No, I couldn't do it.
A lot of poly people say that they're in a poly relationship because they fell that something is lacking in their mono relationship, be it physical or emotional. How ever, something I have see reading a lot of stories from poly people about their relationships is that despite that fact that they preach communication is important, it's something that they don't practice at all.
Communication isn't just about informing your partner about who you're going to bang or date that night, it's about really talking about how your lives are going to be together. Relationships are a partnership, like a business. If you live together, it's about fiances, chores, and raising a family (if you have one.) It's working together to make sure that your life runs as smoothly as it can. This is way past the new relationship phase that so many poly people seem to be addicted to. You know each others strengths and weaknesses and are willing to help each other. This is being comfortable and vulnerable with each other. Not the I'm so comfortable I can fart in front of my partner type thing, more the It's 3 in the morning and I'm here in the ER asleep while my partner is in surgery getting their appendix taken out because it exploded, and I'm staying here till they come home because I know they need someone here and I want to make sure they're ok, and I know they would do the same for me.
Your partner should be your very best friend, (that you bang) getting to that point is a lot of work and takes a lot of trust, and I don't think I could ever do it again. Poly doesn't seem as emotionally as filling to me.
