My girlfriend is eager for us to do our first threesome together.  She's had several bi experiences in the past and enjoys it.   Can anyone recommend a fun provider who is genuinely into bi?  

I tried to get my gf to indicate a type she prefers but she insists that I pick.  My preference is for someone with a natural body but I am more interested in someone who will give the gf a great time.  She is late 30s with a cute little body.

We are hoping to have this take place in downtown DC or Arlington on Friday April 18.

PMs with recommendations would be appreciated!
