She IS cashing in, if you follow her OFs & IG posts she is living the lavish American Dream. An expensive house on the water, a large boat, a new sports car..etc. Lexa is in that top percentage that's making bank on OFs, MV, Jerkmate, the virtual videos and maybe other platforms.
However, IMHO her POV content with Camera-Man is getting old. Unless it's a sunglasses scene or a decent collab then I'm not buying on MVs. The last time I did a Brazzers subscription was when Blake Blossom was in their last Brazzers House production which are usually good. I found out after paying for a full month you have to pay more to download. So if you want to follow Lexa into mainstream you need to check what the site allows and make sure to uncheck the extra sites they sneak in on the CC screen.
Hopefully she does more mainstream with story driven companies like Digital Playground, Wicked, Missa X or Pure Taboo. People want more BBC content which would be good but she needs to round out her content better. A proper blowbang with Hard-X would be welcomed.
