New User Question

Hello- I just purchased my Helix and have been reading the material here on the Web. SInce I usually release my sperm sitting in a chair with my legs stretched out or on my desk top, I wonder if this type of position is OK for the prostate stimulator. Most of what read suggests that you lay on your side or flat? Has anyone advice on sitting forward or on the edge of a chair. I can't wait until my materials arrive- I will post again as my experience starts and as I lean to use this amazing sounding device!
