A row of very interesting comments so I'll reply to most. Given the topic I am going to use MsFiiire / Lillybloomes as refference
... 100%. I think she is not going to do more than solo stuff. The wildest I can see her do is like MsFiiire.
I agree. But there is the biological clock
Also true. But biological clock
The only sex work Shae has done is the JOI.
Nudity is not really sex.
A lot of girls enjoy exhibitionism of either.
The state of the science is this: when it comes to the motivation of nudity and sex work motivarion, there is intrinsec, inner drive for the love of it, and extrinsic, for the money.
A person with high intrinsec motivation can still start because of money and still love the money.
A lot of the ones who do it just for the money can't figure it out. Some do. There are several way outs: pivoting to a job that can pay the bills, renouncing luxury, getting investments and passive income, marrying wealthy enough. The hot ones live life on easy mode, they are attractive for hiring, dating marrying or just getting mentorship.
I am not sure there is money in progression. Prices are about the same, and the older pics get depreciated.
I get the impression that what works is publishing weekly or biweekly mix of MVP content type with a twist to make it interesting. Some change the clothes, some the focus, some the setting. Shae is mostly about the clothes and cosplaying helps her a lot. I think she has always had a natural motivation to go nude and tease sex. I don't know if she really wants to perform solo sex, that's a different animal.
