I have not had many and at 39 I know I am not likely to have many but last night was the exception!
The dream was a bit odd. I found myself in a strange shower that once I got in, there was not an easy way to get out. Once in the shower, it felt like it was designed to hold my my member in a particular position which turned out to be the way the water flowed. The result was that the stream of water began to stimulate me. I felt unable to move or get out so the stimulation just continued until I could not hold back any more. Everything came flowing out (no contractions) in a strong stream that awakened me. I was thinking that the quantity would not be much since my last experience, it was very little. Much to my surprise, was the amount. After several minutes of enjoying the moment and realizing just how much was there, I grabbed the camera and got this photo.
