Reference for Ketubot 9:6

איבעיא להו בתולה נשאת ברביעי ונבעלת ברביעי ולא חיישינן לאיקרורי דעתא או דלמא בתולה נשאת ברביעי ונבעלת בחמישי דחיישינן לאיקרורי דעתא

The question was asked: A virgin is married on the fourth day [of the week], and the intercourse takes place on the fourth day, and we are not afraid that his temper might cool down? Or perhaps [the meaning is] a virgin is married on the fourth day [of the week], and the intercourse takes place on the fifth day because we are afraid that his temper might cool down?
