Obviously I do not know the sex worker in my fantasy, so I have imbued her with the personality that suits my needs, tough independent perhaps even a little spike, as I'm looking for equality, not a compliant whore or a dominatrix. Just a blokey chic to spend my time with.

I have a prurient fascination with sex workers, I would not be a client, but fantasise about having a relationship with a particular woman.
For sex workers, romantic love and sex are necessarily disparate, but I am not built that way, for me the are intimately intertwined.

I am 62 yo.
I love my wife and children and am never going to leave them.
Some years ago, my wife became unwell, and we are no longer physically or emotionally intimate.
I am not interested in casual sex but am looking for a relationship alongside my existing one (I have my wife's permission).
