A childhood belief about sex

I had a very interesting idea of sex when I was younger. I thought that a man and a woman would go to sleep in the same bed (hence, 'sleeping together) and then at some point during the night the man's penis would make its way over to the female. I thought it stayed there for the rest of the night, and in the morning you would have to carefully take it out. I also thought that the woman's privates could close and open, and so could the mans. When they wanted to have sex, they would open.This was reinforced by the
Howie Day song, Collide which I thought was about sex.

The dawn is breaking
A light shining through
You're barely waking
And I'm tangled up in you
Yeah

I'm open, you're closed
Where I follow, you'll go
I worry I won't see your face
Light up again

I thought Howie Day was a very dirty man, singing about this. He was saying that after having sex, after many tries he wakes up and is 'tangled up' inside of the woman. And I thought that a lot of the time when he wanted to have sex with this woman, she was closed, but he was open.
What a sicko this Howie Day guy is!!!!
Haha!!
