Hmm... it's hard to explain how exactly it might be "triggered," given that it's spontaneous... but let me do my best.

Three of the times this has happened, I've been very mentally aroused. The other three, I was in totally non-sexual settings.

The ones where I was aroused make most sense, so I'll start with those:

Freshest in my memory is the time I had been on a boat (shared sleeping quarters with family, .: no masturbation) for 10 days. When the trip ended, after we'd unloaded all our things, I went below deck to turn off all the equipment, auxiliary power (.: lights), and finally the engine. The engine room was hot and smelled like grease and oil and engines, everything was completely dark, but the engine was still thrumming (and I was extremely turned on---this was the day I had to admit up-front that I have an engine fetish ) ----and when I reached out and grabbed the throttle to turn it off, the vibration from the engine sort of felt like it shot straight through my fingers to my clit. It was one of the most incredible orgasms I've ever had.

The other two where I was turned on were more normal---one was when I was a teenager, giving my boyfriend oral, just happily bobbing away on my knees, both hands busy with him, and *wham* orgasm! I wasn't capable of multiples back in the day and he was a little frustrated and confused that he had to finish himself off...

The other was the first morning I woke up with my current partner. We'd used up the condoms the previous night, so in the morning I was just giving him a handjob and having him finish on my chest (both my hands were busy with him)---and when he came, I did too.

For these settings, I think it makes sense to assume that a combination of 1) not a whole lot of stimulation for the day or two leading up to the event, 2) being extremely turned on, and 3) unconsciously flexing the PC muscles would help. To try it out, you might try not getting off for a couple of consecutive days, and then watching a favorite porn scene with your clothes on and your knitting in your hands to keep them occupied? I can try this a time or two as well to see if something like that happens again.



The other three, and the stifled ones, it's a little harder to say. I don't remember specifically if it's more likely to happen if I hadn't been masturbating regularly, but I'd say it's a fair hypothesis.
Er, strike that, because the next one was where I was visiting an at-the-time-long-dista nce boyfriend in New York. And it was like the 3rd day of my trip. We were walking down some stairs to a subway platform, and (good lawd are there a lot of people in NYC!) finally the people were few-and-far-enough-bet ween that I got a chance to, erm, feel him up a little bit... but there were still too many people to unzip his jeans. I disentangled my hands, we made it down the flight of stairs and onto a platform, a train passed by, and I had an orgasm.

(So, so far I don't know if I can identify any common threads. As far as possible clitoral stimulation from tight clothes, the boat time had long johns and work pants, the next two stories had no clothes, and the next one I think I was wearing a skirt.)

The next one was a few years ago, I was out on my bike at twilight when the river was ridiculously high, and I stopped on a bridge to watch, and (both hands on the hand rail) had an orgasm. I'd assume I was just wearing normal pants, but I have no memory of if I'd gotten off recently.

The very first time it happened I wasn't even remotely suspecting it at all... I was on a road trip with two girl friends from high school. We didn't know much about trip planning and wound up in some city on their around-the-city-circui t during afternoon rush hour. Luckily I was just the route planner/passenger, because when I had an orgasm I was totally unprepared and didn't really know what to do.


Erm, I hope that's helpful, Tuesday? Unfortunately I doubt it is. I ... I guess read some Walt Whitman, and try depriving yourself of orgasms for a day or two, and then kegel like mad when something ambient turns you on?

I can't imagine it happening.
