My ex-wife was a gusher. We always started with me going down on her, then moving on to penetration, when she fully orgasmed and a veritable flood issued from her! I had a fully functional penis, at the time.
Now, when I am having sex with a man or woman, which is not very often, my small, soft penis continuously, slowly streams clear, slippery sex-fluid, which must, obviously, be coming from my prostate gland. It never engorges more than slightly, and I never ejaculate, but have whole-body orgasms from a variety of possible stimuli.
