From some forum, discussion of Cunnilingus:

1st First, before direct contact, your partner should carefully shave everything and treat this place with a column.
2nd Do not take this activity in a bad mood or inappropriate mood. Otherwise, you may just get stunned.
Three And finally the third, the last. You have to trust her as yourself. Is there little that can be in the mind of a woman? There are often cases when she breaks her partner’s neck when his head is between her legs.
