49 f4m submissive masochist seeking ongoing relationship

I'm an otherwise independent professional woman who has a full life- the only thing missing is the right Dom to enjoy that life with. I am interested in fwb or ltr with a monogamous local Dom with a sadistic streak, preferably between the ages of 40 and 55. I believe the mental/emotional aspect of D/s is where the magic is, but I also need to be restrained, spanked/paddled, and used hard. If this sounds interesting to you, I'd love to hear from you
