yay! i'm glad you're here, tony.
i've dated a few monogamous people - one of my current partners feels very strongly about being monogamous because that's just who he is, but he's very accepting of the fact that i'm poly. and i've mostly had good experiences. i tend to be pretty open to dating anyone as long as they're accepting of the fact that i'm poly...i don't care if they choose to be or not. but i agree that for some people it can definitely be an issue. thankfully i've been lucky in that regard
