I have a tri phase cable, something i have never used before and was looking for advice. I was planning to use it using a sound and two rubber loops in the hope I can give myself a HFO,is this a good combination? And is it safe to have the sound inside my penis when I orgasm? It's 8mm diameter.

works fine for me although I use a 6 mm sound. Be sure to clean and lube the sound!
