Summary is a bit misleading. Rather than an physiology seminar, this seminar is more about educating each other on sexual deviancy.
Now normally, a "pervert" in anime just means they like sex a lot or think about it a lot, or want it really badly. Not so in this one, these people are real perverts. They eat insects, trick one another into consuming semen, pee in public, break into one another's houses and do weird stuff to them while they're asleep. If this was the real world, these people would probably be in prison.
I was gonna rate this a 6, but the anime does have some interesting episodes that talk about human psychology and why people end up having these odd sexual desires.
Overall a decent anime, but be forewarned, some of these characters' fetishes are quite revolting.
