Rest assured, I do not want your approval. I have no evidence you have morals. Morality is more than making sure your sex life is normal, by the standards placed on upper-class women of Edwardian times.
People often admire my integrity, and I don't mean my sex life there, and yet one of my poly friends is one of the most moral people I know. She is an incisive and compassionate thinker, who is knowledgable on many subjects and campaigns against bullying, rape, domestic violence and all manner of things. She can be relied on to help others, like a modern-day St Martin.
One interesting thing is that when people try to judge me for not having enough partners, she is straight in, pointing out the intellectual flaws in their arguments, and pointing out the real moral dimensions to sexual activity, such as consent, honesty and responsibility. You can be an immoral person, who has only ever had sex with one person, and ignored their boundaries, and a virtuous person who has had sex with 159 or more.
She'd even defend your right to make your choices, out of principle. Even after reading your silly posts.
What would your acquaintances and family say about you, other than "doesn't have sex a lot"? What's your stance on human rights abuses? Donated to Water Aid recently? Are you an unthinking racist? Do you think about your privileges? What about animal welfare? Considering the hard questions, and making choices? That's morality.
