Anyway, I was really looking forward to him jacking me off and vice versa.
But since you asked: A nonmonogamous person has sex with their partner and others; a poly person has or is open to having committed and concurrent romantic relationships.
For one example: An ethically nonmonogamous woman fucks the boyfriend/husband she loves and other guys she doesn't; a poly woman has two (or more) guys she both loves and fucks.
I have two complaints: one with the world and one with you.
My problem with the world is that it seems to think it is possible to embrace the rights of sex workers and still stigmatize the men who employ them.
I am in a happy monogamish marriage, and I enjoy a very good, vanilla-but-bordering-on-tantric sex life with my wife.
