Vacation. Take a vacation from the slave life every now and then to be your own person for a few days. And don't plan a long break when you can afford the PTO from work style of vacation, more like every other month take three or four days to do this. Get a hotel, stay with a friend or family member, just get away. The distance will help you keep your sanity. Trust me.

Communication is most important. Giving someone that much power over you is dangerous. Communicate beforehand and set the rules and boundaries. Yes, even a slave you have boundaries. Like can you be beaten so bad you need hospitalization? No? That's a boundary. Make sure you talk through EVERYTHING before you commit. Also communicate and agree to a way to exit the situation, revoke consent. At that point all activities stop and anything that happens after can be considered assault and/or rape. Also have a friend that knows what's up and a way to signal them when you are in trouble. Things can get out of hand quickly so be careful.

Hi, nice to see you also made the switch here from lemmynsfw ^^
I personally think that in any such dynamic it should be established that your job, family, friends, finances and health shouldn't be negatively affected by the dynamic.
A master/owner/etc also has a responsibility to look out for you and how you are doing.
Financial independence is definitely a good thing.
Hard limits should be communicated beforehand.
Even if everything works well, any kind of dynamic and relationship benefits from regular communication, everybody should have a personal conversation about how things are going with there partner every 1-2 Months. Even if there's nothing to improve currently, highlight what's been going well and what the other person does that you love. Makes it just better for everybody.
Don't commit to a stranger, it sucks to commit and then find out you are incompatible. If there's a previously established dynamic, build from that gradually to see how it develops and if it works for both people.
And of course always be safe an look out for yourself <3

If you're already willing to move states and be completely submissive to an unknown atranger, why not try getting a citizenship marriage somewhere(Canada is closest and most of your cultural and language background will transfer but whatever works for you). If the slavery is a deal breaker im sure that won't be difficult to work into the conversation. Just something to think about.
