How is it possible for a man never to ejaculate although he has intercourse. My partner has never ejaculated since we has ben ahving intercourse for the past year. He is in his early thirties, and says it is not a problem he just holds it back to avoid any risk of pregancy to his partner. Is it an illness to be unable to ejacualate. Or is my partner afraid to tell the truth that he cannot ejaculate. Is this a common problem in males?
