Curious about what an orgasm feels like for a man? Sure, you could read up on the science behind it in order to learn the basics — which would include elementary things like increased heart rate, elevated blood pressure, and rapid breathing. You might learn that men can orgasm without ejaculation.
The male orgasm is a complex experience. The major function of the male orgasm is to ejaculate sperm, although not all men will ejaculate during an orgasm. Beyond delivering pleasure, the role of the female orgasm is less clear, although it may help move the sperm closer toward the ovum egg.
