It does not bother me in the least AS LONG as it is not like adding or subtracting 10 years or more. I agree with the person saying some of it is for protecting the girls identity, which is a good thing.
As an older gentleman I prefer women who are honest about their age and other atributes ( within reason) a year or two or a couple of pounds is no big deal. If the service is good age and weight don't matter. As long as I know what to expect when I arrive.
