thin dick?

okay I have very specific needs for this. my gf has medical history that makes it so she needs penetrative sex to only be with thinner items, so the huge strap ons I normally see are just not gonna work. she's said probably like the size of an anal play one would work. If possible I'd also love to have one thats a stroker so that we both get pleasure out of it. I have an average sized t dick. I'm totally fine with using a harness or adhesive.
