Maybe. It's not erotic to me ... I'm not turned on by the thought of putting on a condom for anal sex, nor the depiction. (My view of the male anatomy is influenced by many, many years of changing little boys' diapers ...). Teenage boys, I'm told, find just about anything erotic. Girls are less likely to; they're interested in relationship (even if it's an instrumental relationship: I give you sex, you give me status) and can probably tell that they're basically being used as toilets.
That's what I meant by saying they're using "erotic" where they really mean "perverted."
...although state law does not define the word “erotic,” Bolling argued that a Maryland law which prohibits classroom material that “portrays erotic techniques of sexual intercourse,” makes video demonstrations of the use of condoms in anal and oral sex illegal. Bolling argued that if a sexual act is not done for a procreative purpose, it is an erotic technique.
Thus, the six year battle boils down to two questions posed by Bolling in this latest court skirmish: Can the school board legally teach students that homosexuality is innate despite rulings to the contrary by the state’s highest court? And, can the health lessons discuss sex acts other than copulation?
