Lucid Dreaming/steps as a newbie

So, I got a Helix about 2 months ago. First time, felt good, second felt good. Third felt good, and then I fell asleep with it in. I woke up grinding into my bed, and felt an orgasm building, and was sweating, shaking etc, and finally came without ejaculating. I don't know if it was a real traditional one or if the p-tab just stopped the flow, but it was unreal feeling that pulsed from my midsection out through my whole body, lasting about 5-8 seconds. Successive tries have resulted in no progress, but have rather possibly made steps backwards. In that I mean, that during use I can get to where I can feel something building, but if I grind into my bed, I actually ejaculate, perhaps from my penis rubbing the bed.
Which brings me to Lucid Dreaming. I've been able to do this since I was young. Don't do it a lot, more for fun than anything, because as a lot of Lucid Dreamers can testify to, when you awake, you don't feel rested, as conjuring Lucid Dreaming can be taxing on the brain. Anyways, I was drifting off with my Helix inserted and I started to feel something building (I was asleep at the time) and came to orgasm that engulfed my whole body. It felt similar to my third session, but I knew I was asleep. Also, the orgasm was much longer, and I felt as though I could hold it. I had 3-4 of these, then allowed myself to drift into normal sleep.
I have also noticed lately, that I don't leak anymore, where as my first 5-6 sessions I leaked quite a bit.
I generally enjoy the feeling of insertion, but feel maybe the pressure to be a bit too intense directly on my prostate. Not sure, really. I get turned on quite a bit while standing, watching porn, but feel I can't maintain the feeling in a standing position, then have to lay down.
Ahhh, what a journey so far...just thought I would share.
