Oh, the summer before high school I kinda went nuts with the masturbation thing. Carrots, cucumber, zucchini, squash, bananas, hair brush handles, electric toothbrush, etc.. they all met my insides. I have actually never tried ice but it's really intriguing.. I'm going to have to get on that soon.
Bottles, either.. bottles just seem uncomfortable to me.
I was also a humper of teddy bears and pillows for a while. I guess I got past the stage within a few years (I suppose buying myself a couple of vibrators helped), but I wouldn't mind trying a few interesting insertions in the future. Strap-ons intrigue me.
