Even if femdom isn't your thing, it might be a good starting point to ask questions and find a sim that better suits your desires.
My favorite hangout is Velvet Thorn (femdom oriented), as it's a very relaxed and casual community. Even worse is committing to the first stranger that demands to collar you. The worst thing you can do is throw yourself at the feet of the first Dom or Domme you see.
If you're interested in getting to know people, look for a nice and friendly sim, get to know people, and when appropriate see if you can find a mentor you're comfortable with. there's no 'normal day' for a BDSM couple, just like there is none for a vanilla couple. For others, it's more personal and less play. For some, playtime is important and they do it a lot. Some will require chores done on a more or less regular basis, some won't. Neither are two Dom/mes the same, or two subs/slaves.
