I think that's it. She has a job outside of the content, has a partner and like others have said she has bouts of insecurity. She's happily gone months without posting a thing and has fans that stick around regardless so I doubt she cares too much outside of the extra money.
I subscribed years ago and even then she wasn't really that consistent. She'd promise sets, get burnt out, take months away and then come back to repeat the cycle. It's a shame because she's super hot and the content can be good when she tries. Especially the sets where it's less cosplay and just her being slutty and teasing.
I agree though. Hopefully this leads to more adventurous stuff.
