For me it depends on the agency and time of day. I prefer 90 minutes for agencies such as Vogue or Euphoria when I know the warm up will include a casual conversation and a glass or two of wine, especially in early evening.
For late night appointments, when available at specific agencies, and which could be hit or miss, I generally just do an hour, usually after listening to live music at a bar.
What’s funny is that Montreal Hobbying could be a good value, but when you factor in extended time, I find I’m paying what I would in North Jersey, so it’s really not the value it seems. Also we know that 90 minutes outcall is really about 80 minutes or so session time.
I’ve experienced 120 minute appointments with some Euphoria and Vogue girls which were really great, including girls who are challenging to book because of their popularity. Best 120 minute appointment was with Alexis at Good Girls back in the day, when we spent about 45 minutes at bar just chatting.
