If I am spinning plates by being non monogamous, does that mean I have to accept that the women I am dating are also non monogamous? Is it a legitimate position to have, that while I am non monogamous, I expect the women I date to be monogamous?
Different strategies work for different guys and you need to figure out what works for you.
I like the “cheeky” humorous deflection.
For the first question you can say “A gentleman never tells” or some derivation thereof. You aren’t lying you are conveying that you are choosing not to discuss it.
Why lie or tell the truth when you can obfuscate and be intriguing.
As for your second question you should always presume that a woman has multiple choices until she shows loyalty and even then loyalty is only as good as what is shown and can change at any time.
