Why does she ejaculates thick and pungent liquid while having sex ?

You'll have to be more specific, even though I'm pretty sure you think you've already been specific enough. ;)

Are you talking about her natural lubrication? Are you talking about a gush of fluid when she has an orgasm? Are you talking about a discharge and odor that's always present?

More specific info is needed to answer this question.

I'm going to get yelled at for this... but she doesn't have a penis sized clitorus does she?
