I agree, Amanda. Though I technically have naver had another Dominant besides my Master, when I first wandered into the lifestyle a little over 4 years ago, I met a Dominant who claimed to have a lot of experience.
At first he was charming and patient, but as time progressed I saw a different side of him. Thankfully, it was strictly online for me with him, though he did have 2 other real life submissives whom I had the pleasure of meeting.
Unfortunately, one of his submissives was very shy and didn't talk a whole lot when there were a lot of strangers around. He then ordered her that she had to say something to somebody every 5 minutes or he would punishe her severely. I didn't think that was right, but at the time I kept my mouth shut.
Eventually, I decided that he definitely wasn't the one for me. He was more interested in a harem that training (his own words) and that's not what I wanted. So, because I never could catch him online, I sent him an offline message stating basically that I couldn't continue withhim because I didn't feel that we were compatible etc. That I didn't think wearing his collar would be good for either of us...and so on.
Well that night he sought me out in the chat room and ridiculed me in public. Called me a cybering little whore and a wannabe. And a few other choice words as well. I tell you, I nearly left and never came back because of him, but people who I didn't even knew cared one iota about me told me not to leave and explained a few things abotu this guy to me. So I stayed. And I am glad that I did because that is the chatroom where I met my Master a few months later.
Anyway, what I guess I am trying to say is that sometimes it doesn't matter hwo experienced they are either. There are really good new Dominants and really bad experienced ones. Though I do have to agree that I would rather and experienced one than a new one... you just have to be careful what experienced one you take. It was a funny thing too. 2 days after I left him, so did his other 2 submissives after they saw how he hit the roof.
