Lecturer teaches students how to put condom on with the mouth

A lecturer, in the bid to teach her students about safe sex, also taught them an X-rated move - how to put a condom on with the mouth. 

This action which probably took place in a University in Brazil has attracted critics who slammed what she did calling it 'inappropriate', a tremendous lack of respect towards education and society.

A footage shows the woman go down on her knees and put the condom on a plastic penis held by a shell-shocked male pupil. His classmates rolled around with laughter as the X-rated practical demonstration was carried out.
