"Are there men out there who would never go to prostitutes and why?"
I believe so and no. Very early years I felt I would never have a desire for.
I being a man. About two years ago had thoughts, came close, had the money for one but changed my mind last minute. Sex. I wanted it. Desperately. But in the back of my mind knew there wouldn't be feelings, the right feelings when having sex with her, when in her presence. And she was beautiful. Tatted up, not outrageously. And I was wanting her but sexually wanting her. I knew the right feelings wouldn't be present. With either one of us. I speak/mention from experience.
I believe no because there are men who have preferences. We all have preferences. Sure there's other reasons.
