Our cocks give us such lovely feelings don't they. Like you say, the intensity of the pure pleasure as you reach that point of no return and feel that besautiful feeling is indescribable. What a wonderful and gorgeous thing the male penis is. Its looks so beautiful.
The feeling a man gets when his seed pumps out is so intensely pleasurable that I think of his semen as "liquid pleasure". Have you noticed that a lot of men look at their cock when it starts to cum because they want to see the "lovely feeling" shoot out. Its gorgeous isn't it.
