I had an experience last night which I'd like to discuss.
It happened just after four in the morning. I was dreaming. In this very realistic dream I was in bed with a natal blonde woman of my age who I didn't know in real life, but in the dream was clearly someone I knew well. We had drifted into a playful, cosy and comfortable lovemaking position in the bed - my front to her back, and I was getting a very moist (if not actually gushing) response from stroking her genital area with my fingers. And then I began to feel wet as well. At that point I woke up breathing very heavily and with a taught lower abdomen, as if all my muscles down there were clenched. I had to allow a little time for the breathing to ease and the muscles to relax. On the panties that I wore in bed was a round wet patch of clear fluid. It had no smell that I could detect, but then my sense of smell isn't especially acute.
I doffed the panties, and went to the bathroom to clean up in the shower. But before I did, I felt inside the vaginal cleft and discovered that it was well lubricated with a colourless but sticky fluid of some kind. I couldn't tell what the source might be, but it wasn't at all like urine; it was more like KY gel, but runnier.
Back to bed, in fresh panties. The only other effects to note were a sensitive back - it felt a bit itchy - and a feeling of hunger that almost drove me into the kitchen, but it passed. I pondered what might have brought the dream on, where the fluid could have come from if it wasn't pee, and whether I'd just had my first truly orgasmic sensation. Then I drifted off to sleep again, none the wiser.
So what actually happened?
In the morning the round wet patch on those panties had dried to a round, stiff but still colourless patch. There was still no smell. Not urine, then.
Given that I'd undoubtedly simulated a sexual experience in my mind, I considered the possible sources of the clear fluid, and how it had been delivered. Obviously it couldn't possibly be sperm-laden semen ejaculated in the male manner. And I hadn't been aware of any muscular contractions to pump the stuff along my urethra - although this impression wasn't conclusive, because I'd been asleep at the critical moment! But it might be sperm-free seminal fluid leaking from the prostate (it's still there of course), fed by the seminal vesicles (also still there) - see Wikipedia at http://en.wikipedia.org/wiki/Prostate, and http://en.wikipedia.org/wiki/Seminal_vesicle. That said, the fluid was colourless, not milky. So maybe it originated from the bulbourethral gland (Cowper's gland), which also secretes into the urethra - see http://en.wikipedia.org/wiki/Bulbourethral_gland. Obviously I can speculate no further without advice from a specialist, but my best guess is that the source of the mysterious fluid was one of these organs.
I can't say that I'm entirely happy about the prostate being involved in any orgasm I might achieve from now on. I thought that, post-op, it would go into a peaceful retirement and stay there!
And although it may be a kind of bonus to know that a lubricatory fluid can gush when sexually stimulated, this isn't the mucus that natal females secrete inside the vagina - it's more akin to the fluid they produce from an active Skene's gland (aka the female prostate: http://en.wikipedia.org/wiki/Skene%27s_gland) and/or from Bartholin's gland (http://en.wikipedia.org/wiki/Bartholin%27s_gland). Oh well, better than nothing!
And what does all this say about my capacity for a proper sex life? I'd say I was making progress.
