I've tried thrice.
First time was with a girl that advertised once on CL as an independant and was looking for a few additional clients.
I emailed her and received a reply. I replied back to her in a few days and didn't hear from her for about 2-3 weeks.
She finally wrote back about 2 weeks later, apologizing for the delay, and mentioning that she's been busy, but will get back to me in the next week.
That was a month ago.
Go figure?
Another girl, that advertised also once, was offering indie massage around Jane & Dundas, but after about a dozen emails back and forth, asked me to text her to set something up (wouldn't give me a number to call).
I mentioned I'm behind the times and don't have text messaging. She replied to contact her via emai. Same thing: I emailed her back and never heard from her again.
Go figure?
A third girl - cute looking, I emailed in Nov. She got back to me about prices and location. I replied that I'd like to set something up - she never got back to me.
Go figure?
This kind of success can drive someone to drink!
