Unreal sex

I have been lurking on here for about a year.Just trying all the things that are suggested.Well I think I have found my path to the SUPER O.My doc found me to be real low on T and vit.D.I am taking the injections for T and taking 2000 mg of Vit D.I have had hands free orgasm for a while.They are very nice but when I had the Super O I had a hard time containing my self.It was just way to much for me I did it 2 nights in a row.I was using the helix.I have gotten plenty of HFO from the perdise but never anything from the Helix other then nice feelings.The Super O was so intense that my legs shook totally uncontrollably and the sensations were just to much to take.I know I will try it again but it was almost to much to handle.
