Today on Tyra, teenagers as young as 13 discussed how they have sex on school grounds, sometimes even giving BJs in the classroom while the substitute teacher is sleeping. As one can imagine, Tyra was appalled and gave some of the kids a stern talking-to, but perhaps more disturbingly, she also went into unnecessary detail with some of the parents on hand, pointing out repeatedly that their kids are sexual beings. It was definitely a big cringe-fest for everyone. Then Tyra asked a teenage lesbian to discuss the specifics of her trysts in the back of the classroom during movie days. The kid did such a good job, it sounded like she was reading a Penthouse Forum letter out loud. Clip above.
