I was working in my house recently while totally nude, a normal thing for me. I was only very slightly aroused, mostly due to the fact that I was nude and enjoy being that way. I was providing no physical stimulation and did not even have a full erection, just the soft beginnings of one, but I did have a lot of perfectly clear, thick, fluid dripping out of my penis that was exactly like the "precum" fluid that happens during sexual arousal and activities with my wife. I am an extremely sexually active and experienced, healthy, 60+ year old man but have never experienced this before. It felt very nice but I am wondering just what it was and why it occurred, as does my wife, who was quite intrigued by it. I actually produced more volume of fluid than when sex is involved. No sense of ejaculation or orgasm was felt, just a nice pleasing sensation. Also, what body organ produces the fluid?
