A senior teacher at an exclusive private school on Sydney's northern beaches has resigned after students found his profile on a gay dating website.
The teacher, who had taught at Pittwater House High School for 15 years, was giving a presentation to year 11 students when they saw him type in a strange word as his username to access an educational website.
Several students later Googled the strange word and found it to be the teacher's profile name for a gay dating website.
In the explicit personal profile the teacher described himself as a "40-year-old cuddly bear who is looking for (a) **** buddy/friend for fun."
The profile also contained a description of his genitals and sexual fetishes as well as several naked pictures.
While his face was not visible in the pictures, he was identified by several other distinguishing features.
It is understood the students circulated the pictures around the school after accessing them.
The schools princpal, Richard Morgan, said the teacher had admitted responsibility for the images after they came to the attention of a staff member. He resigned yesterday morning.
"The teacher in question has resigned. Our investigation found that he had crossed the line of his personal life with school life," Mr Morgan said.
"There are not any child protection matters involved. He has not done anything illegal. In fact, we would not have even been aware had it not been stumbled across."
