Have you ever done it before?
Any harms or injuries to you or the product?
Waking up in the middle of the night or not being able to sleep at all because it's distracting?
I just ordered a Helix Syn off Amazon, so now I'm just wondering.

I have always had trouble falling asleep, I tried twice and it was far too distracting so I just pulled it out 4 in the morning after not being able to fall asleep.
I have done it several times with mixed results. Make sure you use lube that will last a long time because if it dries out it will not be fun to wake up with it. I either have vivid sex dreams with orgasms or dreams about needed to go to the bathroom (probably because the lube dried up)
I have a few times and I usually sleep through the night with it in. Not a whole lot happened for me – I much prefer normal sessions.
I have done it with the Progasm and I slept through the night.
