Just my two cents here, but I would think it’d be best to meet and just hang out beforehand to make sure you two have some sort of chemistry before you go forward with actually camming and making videos together. However, if that’s not an option and you’re totally set on doing this, there’s a few things you can do to make sure you’re protected.
Keep your legal name to yourself. It doesn’t matter how long you’ve been talking to this person, you still don’t actually know her. I’d also keep any and all personal information to myself, including address as well. You two could split the cost for a hotel room or air b&b type deal instead of camming/filming from one of your places.
As far as payments go, if you’re camming, you can cam from your own separate rooms and make your goals the same as one another’s. If one person has reached their goal first, they don’t set a new one until the other person’s goal is met. That way it’s fair and you guys are making roughly the same amount of money so no one has to send the other person money. But if it does end up being to where you need to send money (like if y’all rent a place), do it through something without your real name attached.
For videos, it’s much better to do a content trade. Neither of you will end up having the same video as the other, which is more fair because if you two posted the same video, one person is bound to sell it more which can lead to upset feelings. It also gives one person the chance to undercut the prices (this has personally happened to me), which again, can lead to some upset feelings. If you trade content the other person gets the right to do whatever they want with it just like you can sell your videos wherever you want for however much (unless of course you discuss not posting to certain sites or something like that).
Last thing, if you’re planning on swapping fluids at all, both of you need to get an up to date std test. Do not trust anyone at all who just says they are clean. This should be a given, but yeah.
I will say, from my personal experiences with camming with people who I met through camming and also camming with people I knew before I ever started camming, it’s not really worth it.
