That's true, sex work is different to other work in material ways, some better, many worse. And some of these would persist into the lower stages of Socialism, as much as we might wish it would not.

But there's also a sense in which there are a series of jobs most people would prefer at least some types of sex work to.

I mean, working in a demeaning lab where I am harassed and mistreated and exposed to dangerous chemicals on my bare skin is also a commoditization of access to my body, just not as obvious a one.

Would I prefer to be a sex worker rather than work at the really terrible dangerous job I actually held?...probably not...but mostly because being a sex worker seems like a lot of effort and I am opposed to effort on basic principle.

The Soviets treated manual jobs that had dangerous or socially detrimental outcomes with increased pay, lowered working hours, early retirement, and social prestige. I don't think sex work should be valorized, I do think sex workers should be, at least until we move up the rungs of low-stage Socialism.
