I'm not sure a girl would really be a willing and contented participant if she didn't actually enjoy it and that would probably show in her service but at least we are saying it's consensual.
A few people appear to be judging on this post but given we are paying for sex and the majority of the public would judge anything we do harshly it's a bit "glass houses" really.
Others post on here about punting trannies and taking it up the wrong un with a strap on which isn't my thing but it's different strokes for different folks so long as everything is done willingly.
Some girls do actually like rough sex though they are quite rare and often their prices tend to be higher but I guess it's a niche price for a niche service.
I've punted girls who advertised rough sex on their profile and agreed a role play scenario up front then agreed on safe words etc and sought reassurance during the punt that the girl was actually OK with what was happening only to be told I wasn't being rough enough and to slap her face harder.
I've also punted a girl who advertised rough sex but the reality was she didn't like it / didn't really offer it, once I realised this then I proceeded with a normal punt as to have been rough wouldn't have been consensual.
I've also punted parlour girls who during missionary have taken my hand and placed it on their throat which led to discussion about what else they liked and how hard could I pull hair etc, one girl said she liked to be choked until she was almost passing out but I wasn't comfortable going to the edge in case something bad happened so held back.
So yes I do enjoy rough sex but it all depends on the girl and whether she is 100% into it too, on the other hand I also like a proper GFE with plenty of sensual DFK etc, variety as they say is the spice of life so let's not be too quick to judge other punters for their kinks 
So are you totally precluding the possibility that some girls may not proactively enjoy the sex work but willingly do it just for money and be contented on that basis. basically like alot of people in all walks of life do , isnt this just a pragmatic reality , people do jobs they dont like , nobody is holding a gun to anyones head , people do jobs they dont like willingly and can be contented.
I guess the philosophical question is wether sex work is or should be any different ? should sex workers only be sex workers if they actually enjoy having sex as per a sex worker , should we let sex workers make this decision for themselves ? should we as sex consumers morally only use sex workers who actually enjoy it ?
Anyway how can anyone actually tell if a sex worker is genuinely enjoying it ? so how can anyone seriously say they only go with sex workers who enjoy it ?
Personally i think that its ok to be motivated by money to do sex work, not proactively enjoy it but do it as a job and for money, thats just a pragmatic reality of alot of peoles lives. thats my opinion.
Also there may be aspects to the job that maybe pleasurable like the sense of satisfaction and achievment at earning money and also the social side , i know girls who are happy to talk for ages.
And agree about glass houses , theres alot of fault finding and holier than thou on here when the reality is that mums net would put us all in a single basket and condemn the lot of us .
And re your rough sex and hair pulling , not my cup of tea but diferent strokes and at least we are saying it's consensual
One last thought that strikes me is that if i was a hooker for example , i would be doing it for the money plain and simple , id probably have days when i enjoyed it and days when i had to grit my teeth , but id be asking why all you guys feel the need to be wringing your consciences about if hookers enjoy it , so long as they do it consentingly and you keep paying your money over then just what are you worrying about
