Yes, but they come up less frequently in discussions because they're less prevalent. Anyone can have sex, but fewer people can do something like being a wrestler, which also tends to be a crappy job except for a few superstars. Even those superstars can't do the job for very long before physical or emotional breakdown settles in.

Sex "work" is a "job" where the less experienced you are, the more "employers" will want you. What other job prefers inexperienced people? Only exploitative ones do.
