What should I do after intercourse?

Among the etiquettes of intercourse:

1. Cleansing oneself after intercourse. 'Aisha, may Allah be pleased with her, used to say: "It is befitting for a woman, if she is wise, to keep a piece of cloth. When her husband has intercourse with her, she should hand it to him so he may wipe himself, then she wipes herself, and they can pray in those same clothes."

2. Performing Ghusl (ritual bath) or Wudu' (ablution) if one wishes to resume intercourse, based on the saying of the Prophet, peace and blessings of Allah be upon him: "This is purer, better, and cleaner."

And Allah knows best.
