id say the same as the others, although i would add that to begin with completing a checklist is a good idea, after all you are looking to get into a D/s relationship and it gives you both an indication of future mutual likes dislikes and no goes, otherwise while you might get on like a house on fire what happens if you have absolutely nothing in common when it comes to D/s 24/7 and any bdsm play which after all is what you are both looking for long term.
thats what Icehawk and myself did, we got to know each other by learning about each other both the 'vanilla' and D/s side at the same time, we had some simple rules in place from the very beginning as a sort of guideline,and plans for future rules.i dont mean all were rules as in the usual do this dont do that sense but what i guess you could call mutual goals to aim for, relationships are like anything in life somethings do just click but somethings have to be worked at too.
we knew what we wanted but we also knew rome wasnt built in a day.
