I don't think my clients are abusers. I have met some jerks, to be sure, but the majority of the men I see seem perfectly normal. I feel that many of them are nice people. This doesn't mean that all punters are nice guys - only that the ones I see seem to be. While some of you may think that any man who purchases sex from another person is automatically an abuser, much in the same way any adult who has sex with someone under age, I don't think it's necessarily wrong to purchase sex and I do think that I have the capacity to consent.
That I can choose to see only the good clients is down to two reasons that I can think of. First, I market myself to appeal to the nice gentlemen. There's a reason they choose me over the £35 parlour and the £60 attractive young Eastern European so-called independent and it's not that I'm such a stunner. The men I see often express to me that they want nothing to do with women who aren't happy to be doing it. As deluded as you may see it to be, they really want to have sex with a horny woman who loves her job. (Such women exist although in my opinion very few women are motivated primarily by a love for sex with strangers with the money being a bonus. I'm guessing most of the women in my category don't mind sex with strangers and sometimes find it enjoyable as a bonus. I have only anecdata for that.) I am privileged enough to have the education and eloquence to market myself to this sort of clientele and I have access to the Internet, computers, etc so that I can set myself up in this manner. A woman who works on the street as and when she has an immediate pressing need for cash does not have this privilege. A woman who has to work in a brothel because she can't sit back in her privately leased flat and surf the 'Net until a good client calls does not have that privilege.
Second, I screen very stringently. I will only see men who sound as if they are happy people. I will ignore any communications in text speak, that call me "babe" or "hun" or that ask silly questions (my advertising contains everything they need to know. If they obviously aren't reading that, they're not the client for me.) Even though there are days I may make literally NO money, I never waver in my screening. If I don't like the sound of someone, I won't see them.
Again, my privilege allows me to do this. I am in the position of having money in the bank, plenty of access to credit, and a stable working situation so I can look forward to tomorrow being better. I can also travel to other cities where there is better money because I am able to book a hotel online with my credit card, etc.
