What causes the males d to get hard?

(btw it is a real question)

At the point when men become sexually stimulated, hormones, muscles, nerves, and veins all work with each other to make an erection. Nerve signals, sent from the cerebrum to the penis, invigorate muscles to unwind. This, thus, permits blood to stream to the tissue in the penis.

Explanation:

When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with one another to create an erection. Nerve signals, sent from the brain to the penis, stimulate muscles to relax. This, in turn, allows blood to flow to the tissue in the penis.
