Semen is the liquid that contains sperm and comes out of your penis when you ejaculate
Your testicles make millions of sperm, which go into the epididymis to mature. Then they travel through a long tube called the vas deferens on their way to the urethra and out the penis.

What is an erection?
An erection is when your penis gets bigger and stiff (erect). Erections happen when you're sexually aroused and is made possible by both physical and mental factors.
During an erection, the spaces inside your penis fill with blood, making the penis longer, wider, and more firm. Your penis fills with blood because the arteries that bring blood into the penis widen so more blood flows in, and the veins constrict so less blood flows out.

Ejaculation is the release of semen from your penis. Sexual stimulation causes an orgasm (the peak of sexual excitement). During an orgasm, muscles squeeze and push semen into your urethra and out your penis.
What happens after ejaculation?
After ejaculation happens or if sexual stimulation stops, more blood flows out of your penis and less flows in, causing your penis to get limp. Another erection can’t happen for a period of time, usually about 20 minutes in young men.
