I was going to suggest the position lovetoread has in the photo...in the bath with the water dribbling. Gawd, I loved to watch her do that. Great photo. Great memories.
Good listing on here...you do have the fingers, toys, various fruits and veggies (make sure you clean them well first or put a condom on them)...One of my frends has a cute cubie neighbor at work...so she uses him too....Look around your house and find objects which do not have sharp points and are the size or approximate size you want...then clean it up and there you go...
My college roomie used to use a suave naturals shampoo bottle...it all depends on what your going for.....
