Just some basic techniques for people who need an idea that extends beyond their hands.
I've been masturbating since about 5th grade, receiving my first orgasm from humping a stuffed animal when staying home from school one day. Since then, I've tried many other things.
First, there was the vibrating pillow, which was fun and quiet, but not strong enough and it smelled like my grandma's house. My mom has always owned those super powered back massagers which are great, but they make a lot of noise. I turn on techno music to muffle out the noise.
Also, I became quite fond of straddling the bath tub faucet, discovering that it was easily disguisable.
Then, I got the idea of the hair brush handle, which is still a favorite.
Also, I have this Sailor Moon Wand toy which is nicely shaped at the bottom and wider than most hairbrush handles. I recommend investing in one (or something similar).
My current favorite is using the hair brush or Sailor Moon toy in conjunction with the back massager.
