One rule of communication for sex workers is respond but never initiate contact. First of all, contacting people who you have seen before can look kind of desperate. There are times when you might actually be desperate because your income depends upon contact with others. Unfortunately, desperation does not broadcast sexiness. Naturally, if you contact someone at a bad time someone might find out what the guy’s up to. That’s the obvious reason behind the prohibition but the first reason will scare off even eligible bachelors!
