A) Like someone else said, I imagine with her having a kid, things come up and it'd be ridiculous to begin trashing her without knowing the full story or an explanation.
B) I think we should be lucky she even does private sessions (since a lot of ladies DON'T), and it may relate to something Mutiny once said. She had stated once that during a few sessions she had people thinking she'd do more than just wrestle, based on the kinds of videos she had done. Dragon Lily has done a LOT of sex based wrestling and may have encountered a bunch of jerks who assume she'll fuck them while wrestling, therefore she's just being careful. That's HER decision and if it works for her, then that's ok. I'm sure she understands she'll lose some sessions over it, but I'm sure she's doing just fine.
