No. Retrograde and delayed ejaculation are different terms. Specifically, retrograde ejaculation is a condition present when a man masturbates and has sexual intercourse. His semen does not go out through the urethra, but returns to the bladder and mixes with the urine.
In contrast, delayed ejaculation only occurs when the man has sex. It is a sexual dysfunction in which the man is not able to ejaculate and it takes a long time to reach orgasm. However, men with delayed ejaculation do not have a problem masturbating unlike in retrograde ejaculation.
