500-1? 500-to-fucking-1? I don't think you comprehend how insane this society would seem to us.
To put this in perspective, my old high school graduating class has a little over 3,000 kids in it. So out of those 3,000 people, only seven or eight would be men, maybe even less.
And the cultural differences, Jesus Christ. If you're a 1/500 person, good luck ever going anywhere alone. Your family/tribe/group/pod/-whatever the fuck wouldn't leave you out of their sights for an instant.
Personal freedoms? Tough shit, boy. I hope you didn't have plans of running for political office, because the organs between your legs are far more valuable than anything your pretty little mouth has to say.
Oh, and let's talk about safety too. Even in a more civilized setting, your ass is in danger 24/7. If you went anywhere alone, there's a very real chance that you will be kidnapped, either by slavers, gangs, or a sick individual. This is the part where you say: "Oh hell yeah, time to drown in pussy!" Wrong. You will be used and abused constantly in a darkly realistic manner, because you are a precious commodity. STDs, rape with foreign objects, being pimped out to murderers, yeah, enjoy your new life as an object. Also, say goodbye to everyone you knew from childhood, because you probably won't be seeing them ever again.
It's very hard to imagine this sort of setting, since we live in an almost strictly 50:50 ratio world. But if these women are anything like the humans on Earth, I don't think it will end too well for the men.
That's not to say that there wouldn't be a possibility for having a good life, but most men will not have a peaceful life.
