Help explaining what happened

Hello all.

im still fairly new to this all and have been on the forum for a very short while.

I haven’t had the big “O” yet but have been getting some good feelings during my last couple sessions.

I took a break from it all for a couple weeks and had some spare time today to just “play.”

At about 25 to 30 minutes in to using my syn helix on very low vibration setting, things started to feel good. I was laying on my side, doing some muscle exercises and the low vibration setting turned on just amplified things. I found myself grinding or thrusting my hips slightly and I felt something building. However it wasn’t a dry orgasm, it was wet. 
Im trying to understand what type of orgasm this was, even though I had no penile touch. I doubt this was a super O because I didn’t leave my body or any experiences like that. Yes it still felt good, which is a plus.

Can anyone shed some light on this for me or anyone experienced this same orgasm type? I thought it was all suppose to be dry orgasm is all.

Thanks in advance!
