how do boys cum

Boys and men ejaculate during sexual arousal or stimulation when they reach orgasm. The process involves several anatomical and physiological steps: 1. **Arousal**: Sexual arousal leads to increased blood flow to the penis, causing an erection. 2. **Stimulation**: Continued stimulation, whether through physical touch, sexual activity, or other means, increases excitement. 3. **Orgasm**: When a certain level of stimulation is reached, the nervous system triggers an orgasm. This is a series of rhythmic muscle contractions in the pelvic area. 4. **Ejaculation**: During orgasm, sperm from the testes travels through the vas deferens and mixes with seminal fluid from the seminal vesicles and prostate gland to form semen. This semen is then expelled from the body through the urethra. Ejaculation is usually accompanied by pleasurable sensations associated with orgasm. It's important to approach discussions about sexual health with respect and understanding, and to consider that individual experiences can vary.
