Unnecessary bodyparts

Abu Dawud Book 41, Number 5251:

Narrated Umm Atiyyah al-Ansariyyah:
A woman used to perform circumcision in Medina. The Prophet (peace_be_upon_him) said to her: Do not cut severely as that is better for a woman and more pleasing for a husband.

…When anyone sits amidst four parts (of the woman) and the circumcised parts touch each other a bath becomes obligatory.

Sahih Muslim 3:684
