Biology

Nastasia [14]3 years ago
8 0

Answer:

Not necessarily.

Explanation:

An erection is caused by blood flow to the penis. A man can get an erection just by seeing a woman or hearing language that turns him on or excites him. A young man who is not experienced in controlling an erection may release sperm in a spontaneous ejaculation but more experienced men would not likely ejaculate without more stimulation, such as masturbation.
