Musnad Ahmad 1153:1635

Sufyan ibn 'Uyaynah narrated to us, from Mansur, from Ibrahim, from 'Alqamah, from 'Aishah, that the Prophet, peace and blessings of Allah be upon him, used to kiss while he was fasting, and he used to touch [his wives] while he was fasting, and he was the most capable among you in controlling his desire.
