Finally got great results and orgasmic pleasure peaks. I have to say what did it for me was surrounding my penis with a soft crushed velvet short haired blanket after my hips went through voluntary and involuntary thrusting. Normally when the area underneath the head of my penis gets stimulation it leads to a wet orgasm provided I'm horny enough, but somehow with the Helix in I've noticed that only the most vigorous jacking off motion will produce that result, mild hip thrusting and rubbing of the underside of the head of my penis doesn't seem to commonly trigger wet orgasm. I surmise this path to multiple orgasms worked for me because my brain has been trained with decades of traditional style masturbation stimulation, but combined with the prostate stimulation it is just one of many stimulations working at once and my brain can't single out the penis pleasure to trigger a wet orgasm, instead it just drove to multiple non-ejaculatory orgasms. These were not the most powerful hands free orgasms I've ever had but it's the first time I've had success achieving it through prostate stimulation (albeit not prostate stimulation alone). Hopefully the level of orgasm will increase for me, but it was really good. Anyway I guess this goes against the common wisdom but it worked for me. The soft stimulation blanket material around my penis was absolutely critical. I'd think that a slick satiny smooth matierial would probably work as well, but I have know for years that this particular type of material is like a mink glove or something (never experienced that but saw it in a james bond movie and figure it must be similar to the stimulation this blanket provides).
Congratulations!!!
