Before I masturbate, I come on here and read the daily stories(I love this site, by the way). Then, depending on what time it is and what I'm doing. If I'm gonna take a shower, I turn on the water (bath first) and get in. Then I lie down and scoot up so that my clit is underneath the thing that the water comes out of (having a brain fart right now). And I just sit there but sometimes I will switch the temperature of the water back and forth from warm/hot to cold and back again. This definitely feels awesome but I usually only do this if I'm not totally in the mood. I usually last about 5-15 minutes doing it this way.
My other technique is using an electric toothbrush. This is the most intense and powerful method. I usually use it in bed. I wait til I'm at least 90% sure that everyone in my family is asleep (doesn't take too long, except for my dad). Then I make sure that I'm under the covers and get started! Unfortunately I don't have one of those professional vibrators (I'm only 15) so the toothbrush only has one level of power. I usually only last about 1-5(maybe 10) minutes this way, it depends on the brush I'm using (don't worry, I use a completely different toothbrush to brush my teeth).
That's it for now! I have to go use my toothbrush!
