RP: I have to say that this is my planned approach too.
I don't want to waste a lot of time skirting the issue and it is an intense issue, but I hope that my personality and my body language are able to deliver that issue well. Furthermore, I'd hate to ask someone out and then after they say yes and before the date they learn that I'm married and am poly from someone else. Like that person can say it better or for me. I want to be the person who tells them. Doing so sooner than later ensures that.
