Well you're going to be using backpage from time to time, but as you said, do your research and make sure you know what you're going into. Escorts-canada and perb have ads, smaller selection though. Stay away from Kingdom99, garbage website. I'd reccomend only seeing a well reviewed girl but even that can be scary. I recently seen a reputable sp having somebody pose as them on backpage. It was 35+ year old courtney (spinner). Ad says she was 21 lol and the pics didnt look original, as if they were screen shot, stretched and cropped poorly.
Without going into detail about services etc, I'll name a few ladies you can trust and make you feel comfortable. These ladies will not be bruised, stab you, have linguring guests outside, live in a floor matreess shithole or smell like an ashtray.
Felina Rose, Paige (ek), Kayla (shedevil), Curvy Woman (st james), Red (ad is on ec aka escorts canada), Raven (formerly Brooklyn), Riley (ec)
And if you like bbws there is Zoe Zee and Kaylee Kisses. Keep in mind Kaylee plays super safe and although she makes you comfortable, she wasn't the most exciting one out of the options.
Seen them all, I wish I had more to recommend but this city has crap to choose from. Maybe more guys will give you some suggestions. Touring gals may be an option too, if you have a deeeeeeeeeeeeeeEEEEEEEEEEEEEeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep wallet.
