It's funny, last summer I witnessed a conversation between two of my aunts. Aunt #1's stepson (18 yrs old) was not at the party, it was explained, because he was out with his long-distance girlfriend, who had driven three hours to spend the weekend with him at their house. Aunt #2 acts surprised and confirms that the girlfriend is sleeping IN the house, and asks how close. Aunt #1 practically falls all over herself explaining that it's not too close, because -get this- she and her husband are sleeping on a mattress on the floor in between her stepson's room and the room that the girlfriend is sleeping in.
Meanwhile, I'm sitting on the couch barely containing my laughter- because hello? They're not at the party that they were supposed to be at because they're driving around together, alone! As if they can't have sex in the car! I just shake my head every time I think of it. I don't mean to imply that they definitely are having sex. For all I know, they're not. But people who think they can stop it by physically separating teenagers whenever they get the chance are kidding themselves! No, I'm not saying people should allow something in their house that they're not comfortable with, but to me, it's ridiculous to judge or shame another parent for accepting their teenager's sex life by encouraging responsibility, and not necessarily forbidding same bedroom/nighttime contact. I know that it never, ever stopped me as a teen!
