You are a kindred spirit my friend. I also prefer extreme exposure but only if my "plaything" enjoys these situations. In my case she enjoyed that aspect A LOT so she was trained to voluntarily entice me to put her in these positions...nor argument here.
Since you have not chosen to describe what you have done, I'll give you a few of my favorites:
1) Tied face down without movement ability on the bed with a very high pillow,etc under abdomen as to have the ass elevated as high as possible exposing the important parts for teasing and anal play. Here head is gently pulled back by the hair as far as comfortable and she is directed to beg for any pleasure she will receive. She must continue to properly beg or pleasure will discontinue.
2)If you have a large ottoman this can be really useful...either face up or face down. Face up have the ankles tied to the same legs that you will bind the wrists. some padding at the small of the back will allow more arch. Face down, the same thing, but off center as to allow the genital areas to protrude off the end off the cushion completely exposed. both of these are also excellent punishment positions.
3)If you have a large footboard on your bed this makes an excellent "rack" type device and allows for a large "spread" again with propping at the small of the back to allow the breasts to be more properly 'offered" for amusement.
Hope this helps...
