Having just seen the AW profile - and been its 22nd view - it's clearly aiming at the tiny market (women clients) with the larger one as an afterthought. That's the wrong way round.
I don't know how many women browse AW looking for men to pay, but it must be a very small fraction of the number of men. Even if were a larger number, you are one of currently 3,007 very optimistic men offering sex to women in London.
Female clients exist, but if you find them on AW, go out and buy a lottery ticket because it's your very lucky day.
What do you have to offer men? Put it in the profile. What do you have to offer a M/F couple looking for a MMF threesome? There won't be anything like as many, but put that in the profile. Then's the time to think about what you have to offer women.
