Do any of the larger, no so in-shape hobbyists wear shirts when they are with their providers, and if so have you ever had a provider give you a hard time about it?

Mine wouldn't have a problem with it.That's what i like about these ladies,their very accommodating.Just ask her!...Have fun.

I'm not "large", just somewhat overweight, but I do wear shirts to appointments.  Not a single provider mentioned anything about it.  Besides, I took off my shirt anyway shortly after arriving at her incall.
