I think A/all have a submissive and/or Dominant streak in them. Vanilla are at times those who have never been properly introduced to BDSM. While all BDSM kinks are not for everyone, there is something for all tastes. But nothing can happen, vanilla or otherwise without trust and respect. Communication and taking your time is tantamount to having a safe and successful relationship, it is much easier to do damage physically, mentally and emotionally in a BDSM relationship. Take your time and go slowly, discuss what felt comfortable and what did not, do not push limits before both parties are ready. By using those keys you can have a very successful journey from a vanilla to a bdsm relationship.
