Master and I began as an online couple in a D/s chatroom, but neither of us was attached at the time and we had every intention of becoming real life if all went well. It did, we did and were blissfully happy, (even though we were long distance the entire 5 years of our union) until Master's death on June 6 of this year.
I personally, could never be in an online only relationship. To others, that is the only way they want to go. As Warbaby said, it can be both. "peace" ~blizz~
