The production factory of your semen is on an industrial scale, constructed from multiple locations in your genitourinary system. First there are the stars of the show, your spermatozoa, which are naturally synthesised in the seminiferous tubules within your testicles. During the ejaculation process, these then pass through your ejaculatory ducts and blend with fluids from your prostate, seminal vesicles and bulbourethral glands. This melting pot forms your semen as it arrives via urethral meatus (the end of your penis) to the cold light of day – or night.
Try this: just reduce how much porn you consume in a week. If you want to take it a step further, watch it with your partner. Use it to inspire your sex life, not replace it. Keep in mind that fatigue plays a big role in your ability to keep an erection. Watching too much porn and subsequently masturbating to it could tire you out for actual sex with a partner later on. Balance is key.
Achieving an erection is a complex process involving the brain, hormones, nerves, muscles and blood circulation. If something interferes with this process, the result may be erectile dysfunction. In some cases, erectile dysfunction is the first sign of other serious underlying health conditions, such as cardiovascular problems, that need treatment because erectile dysfunction can share the same risk factors for heart attacks and strokes.
