Personally, I would avoid leolist because it’s a lot of fake advertisement and scams. I would take a look at Twitter , Ottawa independent Companions , Tryst , Vipfavours and of course if she doesn’t mind spas : Brass, Paradise,Cmj.
Also when you contact the ladie , you can mention that’s her first time and if you’ll be participating.
I get messages from time to time about that kind of services and most of the time they’re time wasters so I would also suggest that you have a reference or some way to prove that you are serious about your inquiry. Perhaps a deposit since you’ll be the one paying for her time.
Most of the well established ladies have a website where you can find most of the answers to your questions before you contact the provider so reading her website first is always a good way to see if she’s the one.
Happy research and hope you’ll find what you are looking for
kisses
