It was narrated from Hisham bin,'Urwah, from his father that 'Aishah used to say: Wouldn't a woman feel too shy to offer herself to the Prophet P.B.U.H?" Until Allah revealed: "You (0 Muhammad) can postpone (the turn of) whom you will of them (your wives), and you may receive whom you Will., She said: "Then I said: 'Your Lord is quick to make things easy for you.''' (Sahih)
