My first thought would be honesty, and after reading the post you mentioned above I see that reflected there as well. I'm fairly new to this, but in my short time I have learned that it is important for an OL/LD sub to be open and honest about themselves and to communicate. We only hurt ourselves and potentially any Dom/me that we are involved with by being otherwise.

I think new subs need to also realize that an OL/LD relationship can be very real with emotional attachments and should not be taken lightly.

If it's just an OL scene, then the level of experience should be shared and there should be a safeword or an understood method of stopping the scene should it cross the mental boundaries. I've had experiences both ways, and when jumping into a scene, especially with a newer Dom, it can get very uncomfortable and potentially scare the sub away from the lifestyle. But when done right, especially if a scene needs to be stopped and the Dom/me acts quickly when the stop cue is used, it can be beneficial and a growth experience.

A sub should not come in with no knowledge, they need to take responsibility for their own preliminary education. And not jump on the first Dom/me that comes their way, then try to be the typs of sub they are looking for. Again, it comes back to honesty. Be honest about the type of sub you are, and you will eventually find the right type of Dom/me.

Just a newbie's two cents worth.
