Some providers will then you down when they find out your size. When I was at my largest (330 lbs and 6'4"). Turns out I dodged a bullet. His reviews since aren't very good.
Other providers have even advertised about being accepting of larger guys. Mike Gaite was one of these. Had to be one of my best hires. Professional and sensual. I wish he'd come back to Toronto.
Congratulations on the weight loss. I only lost 110 pounds but I know how hard it can be. Be proud of what you've accomplished. If a provider doesn't want to meet with you it's their loss.
