Bonus: she'll be as nervous as you are.

I'm sure it feels like a total crapshoot to take one for the team. Speaking as a lady who has finally got one review from a very very shy UTR friend (thanks, JH!) I know that I'm very customer-service-focused right now precisely *because* I look like a total crapshoot to most guys. I'm more likely to engage in long email exchanges or phone conversations both for screening and so that we can suss each other out without the benefit of reviews. And I'm more likely to ask what you would like once we're face to face, instead of just making assumptions. That might be my slightly submissive nature poking out, though.

I like to think that all the guys (regulars and one-timers alike) I saw before I got that first review had a great time, they always seemed to enjoy themselves

Reviews are like vitamins and nutrients to providers. They can read the Kama Sutra, let all their male relatives and their pastor fuck them raw, even take it up the shoot from gangsta rapper, but until they have a review they just don't have what it takes to be a companion. At least that is what I read in Wik-o-pedia.
