I would like to try to be a bottom but it would have to be with a provider that’s not hung. Any suggestions

TS Celine. Don’t know where you are, but she would match your specs.

I have found that most of the Thai girls I have been with are 6” or less, and not thick. But, you have to assure yourself, through reviews,  size, and if she’s capable of topping. A lot say versatile, but can’t get it to stay up.

First, when you ask questions like this you should tell people where you are looking.
Next, use the search function in that area to find what you’re looking for.

Without knowing what city you hobby in.  

Hey! You haven't even reviewed Celine! How do we know she's real?

Find a GG provider, bring a strap-on with a size you think you can take, then let her go to town on you.

That’s a good idea. Choose your size.
