The induction's effect is more intense each time I use it, and it's something I look forward to experiencing again. At the time, I found the Virtual Plug file to be arousing to listen to, but didn't experience the sensation of being filled. On and off during a ridiculously busy day, I'd notice a buzzing sensation, as though a very thin vibrator was in place...not a bad thing at all! I expect that, like the other files, its intensity will increase with use. What I am loving about this is that my body has stayed "awake" each day...not necessarily constantly aroused, but certainly more sensitive. I am getting there, bit by bit. Goodness...I feel like a kid in a candy store. Next?
