I'm new to this. Well 8 contacted some girls and baught content but never went to see any of them. Do tell me what i can and can't do and how to protect myself. I did get a scam call from the cops once.

Get a burner phone first. Eliminate the chance of scam calls.
You can do with a wg whatever she agrees to do with you. Just like any other girl.
Remember though, that these girls are not looking for love. Just money. Don't get carried away.
