The customary practice in marital relations is for the woman to lie on her back and raise her legs to her chest, and for the man to sit between her thighs on his limbs ready to go, without rocking her belly, but rather embracing her in a firm embrace, kissing her, snorting and grunting, sucking her tongue and biting her lips, penetrating into her and withdrawing until his head appears, forcing it into her; and she does not cease from continuous energetic movements [rahz], lifting up, rubbing, shaking, lifting up, coming down, until finishing. This is called customary fucking [naik al-‘adah], and is generally how coitus is worked up.
