Does this exist?

Yes.

I do mentoring on a consistent basis.

Define for yourself what "being Submissive" means to you.

What skills and talents do you offer: cook? Give foot massage or paint nails? Make BDSM toys?

There are many skills you can learn which you could then in the future offer a Dominant Woman who shows interest in you.

But to me a Submissive is useful to have around, it isn't only about BDSM play. It is the romance, them cooking too.
