In my first entry I mentioned I might try combining my pleasurable day-after effects with traditional masturbation. I did, and the result was one of the strongest orgasms and ejaculation I've had in recent memory; it was quite enjoyable.
That was last night. Early this morning I woke up to involuntary spasms and arousal sensations, as though I were having an Aneros session—but I wasn't! The convulsions literally woke me up. Unfortunately, I was still tired and wasn't in the mood to go for a spin. But there was no stopping the movements and sensations. Frustrated, I got out of bed and started my day—tired, but at least consciously able to suspend what would otherwise have been a pleasurable experience.
It wasn't long before my tiredness caught up with me, and I decided to take a nap. I slept for maybe an hour, and awoke again to the same orgasmic teasing and uncontrollable body movements. This time I was a little less tired, and kind of enjoying the experience, and since I couldn't seem to stop it anyway I gave in to getting the Helix and going for a full session. I practiced some deep breathing, trying to calm my body as much as possible. I focused on bringing the pleasurable sensations into every part of my body, filling me up. By concentrating on keeping my body completely relaxed, I think this helped spur the involuntaries as the only remaining avenue of release for the mounting erotic tension; I don't think I induced any voluntary contractions at all.
