Woah... I cannot believe the comments that have come out of that teachers mouth!!
Surely something like anal penetration should not be a topic of discussion for 15 yr old?? Was it the teacher who brought that topic up, or a student?? Not that it should really make any difference...

I think this guy definately needs to be looked into.

And as for making models of genetalia... I really do not see the point! (unless they were studing gynaecology etc)
It sounds really suss...
