...there are simply some men who can get along with it and some men who cannot....
That's pretty much how it is.
Each man would have to weigh it out individually. Can he handle knowing his girlfriend is the sexual object of so many eyes? Can he handle knowing she's giving that level of intimacy to other people? What concessions would it take to make that acceptable? Is it fair for him to ask her to drop her line of work because he's insecure?
Personally I'd like to think I'd be able to tolerate it with someone I trust. Truth is I'm not sure. I dated a stripper when we were both going to university. She agonized over telling me what she did for a living, but wanted to stop lying to me about it. It was a shock. I told her it didn't matter just to buy myself time to figure out if it did. It certainly added some pressure to the relationship; a relationship that ended up falling apart. So how much did her job impact that? Hard to say. We never argued about her line of work. We did discuss it sometimes, but I think that's the only healthy way to deal with it. If you close the lines of communication, even the most confident person would wonder....
I'd marry an SP. But it would be dependent on other factors. And as much trust as any marriage requires, such a marriage would probably require even more for comfort.
