Okay, I swear I'm not sex obsessed, considering my recent posts.. but I had to ask this >

You know, I always heard/read that you don't really get self-lube -- or if you do, it can take a long time before you get any and there's hardly any.
In my case, I find when I'm turned on there's a lot. I don't even use lube when I'm turned on because I've got plenty going around (more than a few of my ex gf's, to be honest). Then, when I orgasm, i just gush out with a tons more (I usually have to go clean off when I'm done as there's a lot of, er, juice... and no, it's not pee, it's clear, sticky, tastes like it should...)
So, where is it coming from?
Okay, I know that it's some kind of gland (bulbourethral gland / Cowper's gland) somewhere that is a reminate of the boy parts. But I thought went with with the poison factories? Or would be damaged when playing with the urethra or creating the neo-vagina? I can understand it causing the gushing part, but is it producing while I'm turned on as well... or are the vaginal walls producing something, too. They walls inside seem to always be wet, and they don't seem to dry out with action.
I was just wondering. I kinda have an idea... although I'll have to say the amount of self-lube has me surprised.
