Super-O and the aftermath

So last night I had my first true Super-O. And it was amazing.
It really is as intense as people have always made it out to be. I thought that I’d had them before, but man I was wrong.

Now all day I’ve been reminiscing over that experience. My body has had involuntary times when my prostate starts to tingle and my muscles start to convulse. It literally happened in a meeting, and if it wasn’t for my face mask hiding my pleasure, idk what I would’ve done.

Has this happened to anyone else? If so, how often should I expect these random times when my body starts to pleasure itself?

Erections before super-O?

So I’ve been using my massager for a while now, and I’ve been able to reach that magical super-O. Still, everything I read always says that you get a magical and amazing erection prior to that point, and it’s never really happened for me. Does anyone else have that same issue?

I’ve also heard that having a hard cock prior to play is the way to go.

Thoughts?
