I used to have this toy:

I miss it! It was the perfect size for me, and it felt so realistic, it had a kind of 'skin' that moved semi independently from the core. I got rid of it when I left for college, didn't want some snoopy roommate to stumble across it!
Right now, I have a small vibrator that I bought for my girlfriend that she never uses that I use occasionally, but I'm gonna buy that dildo again someday!
