As I'd cut off the curl on the tail of my devices, I thought I'd try using one of them whilst sitting. Bad move. Not much movement and I felt a little sore inside and out afterwards — that's with taking it gently too. You might get away with this with the shorter models, but not with either of mine.
Yesterday's only session was an Anerosless one, but it was interrupted by a phone call (wrong number) at a critical point. I didn't get an opportunity to try later on.
Today, though, I set aside a couple of hours in the early evening for a session. In the event, I only needed one of them.
The session started as normal, but with a slightly quicker onset. One thing I noticed during the build-up was that my legs suddenly felt cold. They were covered by a thick duvet, so that seemed impossible. I can only suspect that this was some change in blood circulation at that point. The thigh muscles were twitching randomly, then other muscle groups gradually joined in, including the facial muscles. Again, there was a lull in activity before the O hit.
When the feelings drained away, I checked the clock. It had been barely half an hour. Not having anything pressing to do, I just relaxed and waited to see if anything else would happen.
It couldn't have been much more than a minute when it started up again, and not much more than a minute after that when I was back in the land of O. It was at that point about the same intensity as the first time.
Then I tried something I tell others not to do. I tried a few little contractions. I reckoned I hadn't anything to lose at this point — I'd already got on to the plateau, so it wouldn't be a disappointment if I fell off. Well, I didn't fall off. A few very gentle nudges later, my prostate area fizzed briefly and a moment afterwards everything became much more intense. I'd rate it about the same level of intensity as the rush you get from a traditional ejaculatory orgasm. This lasted for about ten minutes but seemed like much longer.
I think I can say, "Wow!" at this point.
