Hi Kelly!
May I suggest starting with someone you trust completely? It sounds as though you perhaps played with someone in whom you could not confide? Personally, I think that BDSM games HAVE to be conducted in a trusting relationship,otherwise the whole atmosphere can turn unpleasant.
Also, with someone you like, there is that vital element of wanting to please as well as grabbing for your own pleasure.
Good luck! I know many others will contribute advice too-this is a great place to learn!
