Im replying purely as a hobbyist, but Foxy_lady and Ashlee might be among the few worth visiting.
As someone who has lived in Durham for the last 6 years, (generally) Durham is getting worse by the day in terms of quality and variety.
If you live in Scarborough/ Toronto/ North York/ Mississauga, Id stick to that ... they're hotter, consistent and charge half of what these Durham girls charge....theres a lot of variety and the service is great too.....
but if you decide to visit some of the handful lovely ladies here, avoid transit...either uber or rent a car
