I guess I'm lucky, I haven't had a bad coming out experience (gay or poly) yet. But then I let people get to know me 1st, then tell them. So they know me as "Wil, the guy who happens to be gay and poly" as opposed to "Some gay guy who has like 5 boyfriends, I think his name was Bill". Ppl have a habit of putting stereotypes before individuals, if they don't know the individuals 1st.
I suggest finding a casual way to discuss poly with friends and hear their opinions. Maybe bring up the forum guy.
