Sexual Harassment and Bullying actually increases

J. Jackson (2002) All boys schools create a "macho, male culture where boys are more distracted by each other than they are by girls"

S. Askew and C. Ross (1990) in the book Boys Don't cry: Boys and Sexism in Education says that there is increased harassment and bullying in all boys schools

Michele Paludi (1990) found that same-sex bullying and sexual harassment is just as prevalent in single gender schools as in mixed gender schools.
