Have patience and wait for reviews five and six...

That and stay away from Backpage girls with only one review for $120 for an hour that is model quality/once in a lifetime.

There are guys in the Washington D.C. boards that does mini's all the time and I've been accustomed to seeing their names. Also, there are guys on here that I know are credible reviewers. If they were to write a review for a new provider, then I will not hesitate to see the new provider because I am familiar with the reviewers.

If they are not credible reviewers and someone that I do not recognize, then I will not see the provider. Reviews are important, and so are the reviewers that make those reviews.

You asked how to minimize the risk associated with new providers that have 1 or 2 reviews, and my answer is to make sure the reviewer is credible enough to. You can't just take the word of any old slouch that write reviews.

I have tended to follow Guarddog111's approach after some less-than-ideal experiences many years ago. I am generally very happy with the results.

If you do want to see someone new without many reviews anyway, you can follow TheDollarMenu's advice, but I would add one thing.  

Read through the other reviews of the reviewer to see if your tastes and his match up. If his priority is MILF types with whom he can have a good conversation but yours is quickies with barely legal spinners, his 9/9 may be your 6/6.
