well it helps to write out what are your kinks and limits.
If you don't know what are yours, a good way to start is to do the test on bdsmtest.org
Welcome to the original BDSM Test! Test your kinkiness and find out your kink archetype. Are you into Bondage & Discipline, Dominance & Submission or Sadism & Masochism? BDSMTest will identify your preferences so you can play in consensual activities with others.
bdsmtest.org
it give you a general idea as in what you may or may not aware that you like. And you could expand on that.
A bit more self intro also helps. How you look like, what are your availability, tools you have.
Third, you can look through all the post here and see what are the things interests you, and maybe try to do it but tone it down. For example do 5 spanks when it ask for 50. Get your toe wet before jumping in.
