How does she expect to keep that aspect private when you can find pretty much everything about her on the internet? I think her boyfriend already knows what she does, her family likely knows what she does as does her friends. Does her boyfriend not want to be involved in the videos? Because she could just say that and could be perfectly understandable. It's just so weird that they're trying to keep one side separate from the other when they're plastered all over the net.
Out of her comfort zone, probably his too but that's what it is and she's never fucking strangers either, she answered this on her IG, still there far as I know.
