If semen gets on the pubic hair and the hair is then removed, is it obligatory to wash the area that was affected by the semen after the hair has been removed?

Semen is considered pure by some scholars, thus it does not necessitate washing. For those who deem it impure, if it touches the pubic hair and the hair is subsequently shaved, the skin beneath it does not need to be washed unless there is certainty of the impurity having reached it. In cases of doubt, it is not obligatory to wash or sprinkle water over it, though some scholars hold the view that sprinkling water is necessary.
