Some WILD questions.

[Fengo]

Yesterday was my first time attempting to WILD: Ok so I got in bed and set my alarm to wake me up 5hours later. I tried WILD before bed and it didn't work which is expected. So I woke up at 4:45AM and I tried to WILD. What was weird was that I was going to fall to sleep and my whole body was vibrating and my hearing was muffled and I felt a tickling pain in my booty. Before my hearing was muffled though, there was a intense shriek in my ear What is that ? Then everytime I tried counting from 1 because I switched to a different position It felt like I was getting pulled off. Eventually I just went to sleep because of no success and tried again at 9:20AM. Why is it that I always think about swallowing so I am forced to swallow? Lastly, I'm assuming that SP is the feeling that I get that starts in my legs and arms and feels like .. weird , why is it that it never travels to my stomach/chest/head ? Thanks
