This is another way to take shower after Janaba (sexual intercourse). The difference between methods #1 and #2 is washing the feet at different steps. You’ll see.. (Get method#1 here.)
(the wife of the Prophet) Allah’s Apostle performed ablution like that for the prayer but did not wash his feet. He washed off the discharge from his private parts and then poured water over his body. He withdrew his feet from that place (the place where he took the bath) and then washed them. And that was his way of taking the bath of Janaba.
You can do it either way. Only following the steps while taking a shower can bring you reward. How easy is that? :)
