Emily, it's not because you aren't a spinner and that's not what most men want anyway. You're new and the jerks love to be mean to the new girls. I'm a plump 40 year old and I stay booked with clients who treat me like a lady and respect me. A woman doesn't have to be a size 5 to be considered beautiful.
Don't cry. Eccie is a step up, several steps in fact. Just hang in there, keep your ads up and you'll get good clients. Most of the gents here are nice. There's a thread for providers with tips for new girls and you can always ask for advice in the powder room.
