I have not as many experience as you guys, but here is my top 3 least favorite...
1) Beta-Teste
I refuse to call this my first escort... i mean, it could even be my first sex session period... so i tend to call this the beta-testing, like when a product is not finished and they just test it... Anyway it was in sherbrooke, i was young, fan of strippers, was wasting a lot of money at strippers for nothing much(touching only...) so i tried to contact Douce Extase... i was around maybe 22 or 23... im now 27... Anyway got to the place... the girl look trough the glass, she open, i must have scary her a bit since my friend was with me, he wanted to just "see her" since he was my driver that night. She was like " huh wich one?" and i said me, he just drive me, and then my friend turn around. The girl was not super pretty but not ugly either, more like a girl i wouldn't really give a second look in a bar in a lust way but if she would come to me, i would not turn around. So well... she was supose to do BBJ for 20$ more, the agency said, she refused cause she didn't like my dick(all SPs i saw in montreal didn't mind, and some where extremely freaking hot) So i get a CBJ and remember its my first time... i never had a BJ so for 2 years i tough Blowjobs where not fun.... cause lets face it, with a condom, i think it suck in the bad sense of the word... So i ask for sex after like 10 mins... since i only had half an hour and man she did the star...dead star actually... i pumped her maybe 6-7 time and she was eyes close not moving... i decided to just go back to the BJ cause i didn't want my first experience to be like fucking a sleeping girl... that would be weird... I manage to cum... the session was nearly over, she asked me how it was... i telled the truth, i mentioned i did tell her it was my first time and i was expecting better, she said can't please everybody then i leaved... And i mourned the 100$ i lost that night... when i could had fun at the strip club(wich at that time satisfied me) This scared me of the escort scene for a couple years, thanks to Kim (indy) who came to sherbrooke i got back to it a couple years later.
The next 2 are NOT terrible experiences but more like "the worst i had" but outside that beta test i didn't had one that was horrible like you mentioned above.
2)
Kristina at Angel Escort : Girl was friendly and fun to chat with, but it was too obvious she didn't want to have sex with me. She always stoped during the BJ asking me if it was good... not one time but like 5-6... cmon don't stop damn... lol I didn't go the full round with her(no intercourse) and i was supose to cum in her mouth, it was part of the service based on the listing but she telled me she stoped doing it and asked the owner to remove it, but he didn't yet, so i asked for a big tip if it was ok... she agreed after a couple asking... but when it was time to cum she pulled her hair and pretended it was to ... huh sorry don't know how to say it in english but "pour renifler et evité de me morver dessus...) So she miss totally the CIM and some of it landed in her hair... I was disapointed and of course she didn't got any tip for that... Too bad cause she was pretty, very pretty and the chat was fun. I even telled her at the end would she had been my barber or whatever its call in english, the person who cut your hair, i would had take her again for sure. I said also you can't expect all clients to be collin farrel look-a-like... or whoever you find sexy these days... she didn't really know what to say.
3)
Tabatha at Angel : She came in like she was on speed or something, very controlling, i asked her to remove her lingerie and she refused asking me why i didn't like it... well i just like the girls to be naked... not have stuff in the way... She gave me a very hard BJ, too hard to me, she was not delicate at all, she even almost hurt me to some point, literaly... Sex was brief but good... But it was the first escort(outside beta test) i had trouble cumming, i had to finish up myself over her mouth to CIM. It happened before i could not cum twice... but hey first time was not a problem and it was mostly because time was in the way. But with her i had trouble. Worst of all, she mentioned many time she was kind of in a hurry, so pushing me to cum, and she left when 20 mins was still on the clock... she didn't even shower(but i think she hand washed the pussy cause she stoped at the bathroom, but didn't remove her damn attire)
But to Angel Escorts defense, if i had my 2 worst experience with them, i also had one of my best(Angelina) that i rank execo with another one and another very good one with Tanya(my latest escort) , this remind me i never reviewed her... should do that actually. Tony and Tabatha also offered her a free hour(with Tabatha) but due to restriction on my side(being from sherbrooke, not being able to stay as long as i would, and having to match the free hour with the other girl i want to see, wich can be hard) i never took it. To be honest, i never tough i would say this, but if Tabatha physically was attractive, the session itself didn't inspired me of a repeat...
So i guess you have it... Im still planning to use Angel Escorts, there roster is very impressive visually speaking(cause of the current roster, only saw Tanya wich was a very positive experience) and i like they list the services, allow pre-booking and such. I guess i just had bad lucks. Kristina was very new, Tabatha may had been on substance... anyway they both seem to have got good reviews, so maybe it was me that was the problem for them... For Kristina it was my look obviously... For Tabatha maybe its just me that don't like her type of service... i like soft not rough...
