Part of the problem with SS, is that the definition does vary from couple to couple. You basically do have to ask them what their rules are as soon as you find out they are SS, to assess whether it's something you want to do.

That said, we tend more towards soft-swap and it's simply a comfort factor with my hubby. There are a handful of women he's comfortable enough with to consider a full swap. For us, soft swap, means everything but actual vaginal sex (and we don't/won't do anal).
