Well, the thing about asking for advice is: you don't always get what you want to hear. That is one aspect of asking for advice online, be it good and bad.
2) Your comments about meeting someone for the first time. You're referring to guys you've met in a non-business sense. Remember: you're not dating these guys, you're sleeping with them for money. A life rewarding connection isn't necessary or even desired.
3) As I suspected, his actions seemed to be more of a desire to keep the date going as hoped as opposed to threatening you in any way. Specially since you were in a coffeeshop!!!
4) At $350.00 per hour you had better shape up and quickly. That is at the upper end of the scale in Toronto and you can have truly gorgeous and amazing women for a lot less money.
5) As for getting a few customers at random and avoiding terb. If you stop dates because you're uncomfortable for an unexplained reason, you won't get many customers. It really sounds to me like you're a typical woman selecting your men with the same criteria as you would someone you want to date. I tell you, don't advertise yourself as an sp, because you're not.
6) Your "uncomfortable" feeling. Sorry, Hero is going to jump all over me again for this. But hell, I wasn't there and don't know you from sam, but sleeping with a guy for money IS an uncomfortable situation until you get a few dates under your belt. I really don't think it is fair to the CUSTOMER to have such high expectations of them. We're guys that pay for sex. Get over it. You're NOT going to meet Hugh Grant, Brad Pitt, Mr Right, or some GQ Model...that only happens in Hollywood......
Sorry, this is going to sound harsh but: I really think this is a case of a (as yet unknown to me) attractive woman who thinks she is worth more than the other extremely attractive ladies out there and thinks, hey, I'm a COURTESAN....sorry, you're not. A courtesan who demands a higher than average rate is a woman who will blow a customer's mind and have no hangups about connecting with the customer. Sure, getting along with someone makes the encounter so much better, but you're not going to marry him, date him, take him home to mom. You're going to fuck him for money and at $350.00 per hour, IMO, you'd better be prepared to fuck him like he's never been done before. (sorry, that's harsh, but read the reviews: one can have an amazing time, with some truly wonderful women for about 2/3 of her rate).
Sorry angel, as others have indicated, this business obviously isn't for you.
