Lets define coping, with Wikipedia, as the ability to constantly change cognitive and behavioural efforts to manage specific external and/or internal demands that are appraised as taxing. Of course, by extension, the less we appraise something as taxing, the easier we can cope with it.
Let’s talk specifically about coping with sex work, not about coping with life in general. The two are somewhat linked but someone coping well with life in general may be incapable to cope with sex work as someone stressed out by life in general may be able to cope with sex work.
Lets accept that it is impossible to assess objectively a sex worker’s ability to cope with her job because 1 we cannot know for sure her feeling about her relation to us as a client; 2 we can’t see her ability to cope with other clients; 3 we can’t see her ability to cope with others in her work environment (other sex workers, agency owners, bookers, drivers. etc); and 4 we can’t see her ability to cope with the social pressure over sex work. However we may have a gut feeling about it.
