So Close " I Think". Need Advise again

Hi
After 2 months with my Helix I feel I have now got to the stage of " oh so close but the fat lady is still not singing" feeling.

Last night I followed Carlton`s advise about laying on your back with legs at ten to two position. After a short while the feelings started to rise. Involuntary leg shacking and contractions.A very pleasurable experience then it went a stage further. I got to the stage were I couldn`t workout whether the contractions that was occuring was voluntary or not.
I again followed Carlton advice about pushing as if to goto the toilet then contract again. The feeling wells up inside and I get to the stage of " here it comes" then nothing. All the feelings i`m getting are the best yet. How do I go over to the other side?

regards
