Erection frequency

got something similar to that, i taught i was gonna explode, big orgasm coming, when i look , i was flacid but it felt i was very erect and excitted (penis excitemenent)

Strange business this! It's all to do with the rewiring. It takes time but it does happen. My sessions are so different from when I started four and a half years ago. Sometimes as you have said, you think you are hard and about to have a big orgasm but actually you are just flaccid. I think that the penis is not the be all and end all of the sensations. It responds to the sensations from the prostate and in turn, touching the penis can stimulate the prostate. One other fascinating observation for me is that the aneros use has brought many sensations back from the dead. My glans is now fully recovered in its ability to stoke up the must intense erection sensations , edging has become a delightful renewal and my whole genital region is stirred by even thinking about them. Even when I am driving, if I begin to ponder on my prostate, I start to erect and have to watch out! I'm so pleased I met the Aneros people and the wonderful invention.

As I posted regarding "Woman's question about flacid penis during aneros use"

Regarding a flaccid penis during Aneros use and pegging; it stands to reason with all of the blood flow directed to the prostate, it is understandable that there would not be enough blood pressure to support an erection. The Pro-Dom I have played with says that is correct based on her experience, and frankly I trust her experience. She also said unless you manually stimulate the penis typically, not always the guy will be flaccid.

I often get a quick erection when I insert my Helix, but flaccid most of the remaining time.
But I often get a hard erection usually the first time I go into an intense Dry/Super-O, especially when I have deep thrusting feelings. After the first time, it's 50%-50%, and I've had all the same intense feelings while totally flaccid (which still amazes me by the way.)

It's 50 -50 with me most of the time. When flaccid, it does seem to feel like it is erect sometimes, more like a huge chubby. Cumming while flaccid is very different for me, more like an overflow than shots. The cum is more of a liquid. After this type of orgasm I filled drained and satisfied.
When I cum with a stiff erection, it is almost violent. Aggressive and powerful shots. Many of them.
