A lot of this assumes that both parties would not be monogamous.
I think a relationship is possible between one provider and a S/O.
The older(I prefer mature) I get the less it all seems to matter. It is a business and if recognized for that and accepted as a person's job or career then that is what it is.
For most of my life the idea would have been ludicrous for me to consider. I think a wise person as he lives and learns can break through false paradigms and find new ways to see and enjoy life.
I no longer believe in love and in fact think it is destructive. I do accept short periods of extreme like especially as the bar is closing.
