The difference between Orgasm and Ejaculation

There is a huge difference between having an orgasm and ejaculating. When having an orgasm this is what is happening “There is a combination of things that come in effect when it comes to an orgasm in the brain. Neurotransmitters, and neuro-peptides for example, are heavily involved in the sexual response. To reach an orgasm, the central nervous system sends orders to the heart, so that it pumps faster, sending blood to oxygenate the increase of blood flow in muscles involved in sexual activity. Nitric oxide, serotonin, dopamine, epinephrine, and norepinephrine, are just a few of the neurotransmitters and neuro-peptides involved in sexual activity. Nitric oxide (NO) plays a critical role in both male and female sexuality.” Which is pretty remarkable that all of this is happening in the brain to have orgasm. To have an orgasm is a feeling you get all over your body which is chemicals going off all together. There still much research to do to see how exactly each chemcial fuse together to make an orgasm happen.

To take a detour “In penile erections, NO stimulates the release of guanylate cyclase, which, in turn, converts GTP to cGMP and produces relaxation of smooth muscles and increased blood flow into the penis. This information is used in the popular drug sildenafil (ViagraTM) that inhibits the metabolism of cGMP to prolong the effects of the erection” which I did not know this was the chemical that helps prolong maintain an erection. If you closer into the above paragraph cGMP is meant to increase blood flow which also needs air flow to help keep an erect penis. If you have a hard time keeping an erect penis then exercise, eat vegetable and fruit, stop drinking soda, drink water, stop stressing and you will be able to maintain an erection.

Now ejaculation is the actual release of fluids.

Sexual stimulation and friction provide the impulses that are delivered to the spinal cord and into the brain. Ejaculation is a reflex action controlled by the central nervous system. It is triggered when the sexual act reaches a critical level of excitement. It has two phases.

  • In the first phase, the vas deferent (the tubes that store and transport sperm from the testes) contract to squeeze the sperm toward the base of the penis and the —-prostate gland and seminal vesicles release secretions to make semen. At this stage, the ejaculation is unstoppable.
  • In the second phase, muscles at the base of penis contract every 0.8 seconds and force the semen out of the penis in up to 5 spurts.

The difference is orgasm is a mental thing and ejaculation is an actual release of fluids. In other words you could have multiple orgasms without actually realsing and type of fluid. This goes for both male and femals and usually is more referred to women but as a male you could have multiple orgasms with practice and breathing techniques.
