When it comes to semen volume, if you are comparing yourself to what you see in porn, you better stop right there and think again. Too many people compare themselves to porn and somehow it doesn't sink in that IT'S A MOVIE and some aspects of it are FAKE. A mixture of cornstarch and water to simulate semen can even be used to heighten the effect, especially for shots to the face. And remember, in a movie, a shot can be edited anyway you like, scenes are made to look like they last longer, etc.
Most people have difficulty judging the exact volume of their ejaculate, especially when it's spread out or partly soaked up in a napkin or tissue. On average, guys ejaculate about one teaspoon-worth of semen in one ejaculation (about 5 mL) which is not a large amount. The amount (volume) of ejaculate will be a little more if it's been awhile since you ejaculated and less if you ejaculated recently.
A man's body is constantly producing sperm and storing it up for ejaculation. This gets mixed with fluid produced by the seminal vesicles and prostate. Apart from frequency of ejaculation, the amount of time spent in sexual activity and the amount of arousal can also affect the volume of ejaculate. The longer the build-up, arousal, and direct stimulation prior to ejaculation, the more volume of fluid can be produced to mix with sperm for ejaculation. Some men also have noticed that this increase in ejaculate volume with longer stimulation also produces a waterier semen because of the increased fluid-to-sperm ratio.
So it stands to reason that if you are dehydrated, your volume will probably be less. Other factors that affect it are getting proper amounts of zinc in your diet, getting good sleep, stress levels and your frequency of ejaculation. Genetic factors and age also play a part, but those are not under your control. Strengthening your PC muscles can produce stronger contractions on orgasm and help push out more fluid. I explain how to strengthen your PC muscles by doing Kegel exercises in this article. You can also check out my eBook, A Man’s Guide To Male Sexual Issues.
