If they do not want to see you, they would not let you through the front door. They IMO do not really care about age or attractiveness. Even girls on SA largely do not care so long as you are clean, nice and together. Besides, most of the guys who pay to play are about your age and are not exactly Brad Pitt. For that matter, a lot of AMP girls - not to mention escorts - are not pretty, but wear a lot of makeup and have fake tits and so look decent.
