Interesting question.....I think if a girl contacts a hobbyists that she really likes and is just dying to fuck him, then she should have every right to do that and I'm sure the guy would love it as well. But seeing as the girl is asking to do HER a favor, asking for a donation in that particular case would not be right. I don't know of any guy that would be upset if a girl asked for him to come and fuck her because she was horny. So Kelly and Tara - please put me on your drunk dialing when horny list
But if a girl is just trolling for business and asking every guy in her contact list for an appointment, that crosses the line of what is appropriate. I would feel it out of line for a girl to ask out of the blue to come and see her for no apparent reason and offer nothing more than what was in her latest ad. Since we are reading this on the internet let's make a leap of faith and assume that we can all read. We all know where the provider ad section is found. Let's assume that the guy has read the ads and if he wanted an appointment based on what was written in the ad, then he would contact the girl. For a girl to write me and offer the same thing that was written in her ad insults my intelligence. It says to me - if you're so dumb that you can't read, I'm going to tell you again what I put in my ad.
On the other hand if she is going to write and entice a guy with something that is NOT listed in her ad, go for it. Maybe she is dying to cook something special and wants some company so she doesn't eat alone. Maybe there is a play, sporting event or concert and she wants a companion that she already knows and enjoys their company with an understanding of paid BCD time at the end. Maybe she is just bored and wants to offer an evening or longer amount of time with someone that she enjoys for her normal hour rate. Whatever it is - if the girl has a specific reason to make contact to tell a guy something that isn't already available for him to read, go for it.
