I always lied when I did online roleplay. When I first came online 10 years ago I have very low self-esteem and I felt that no one would want to be with me. So every Dom I played with I told them something different. As Domlord said, it's roleplay, so I took on different personas with each Dom.
I met Master online in a roleplaying game room and W/we connected only as O/our RP characters for a couple of months before W/we started getting to know each other as O/our real selves. Master was the only person I'd met online whom I felt a real connection with (even when W/we first knew each other as O/our RP characters). So when He finally asked me what I looked like, I told Him the truth. And I finally met someone who completely accepted me.
