The penis is an external genital organ involved in sexual intercourse and urination. It contains tissue that fills with blood, becoming erect during sexual arousal. Penises may be circumcised (foreskin removed) or uncircumcised (foreskin intact). Both forms are normal and healthy. Neo penises is a surgically constructed penis through various surgical techniques, such as with the use of penile implants.
