It is part of proper conduct that a man not have sex except when he is erect and the penis is strong, and that he not take a woman upon himself as long as his disposition does not allow it, as he will be having sex with her in flaccid enjoyment. And if the wife covers up a man’s deficiency, and strokes him, and if she is beloved, focusing on his intimacy at the peak of enjoyment, and he does not rely on his penis rising, in the absence of genuine sex drive, then he will only last while he is in between the vagina, and it will be necessary for him to be fervent, and he will end up in a situation more resembling lesbianism [musahaqa, grinding].
