cock barrier

when two straight males, either friends or bros share a bed usually a double or queen size, and have a simple barrier in the middle. A pillow or stack of pillows are common. to avoid any such contact and the possibility of your pricks touching.

Timmy: shit man i wish i didn't have to share the bed with you.

Ron: It's no problem man ill put a stack of pillows in between us, to form a cock barrier.

Timmy: that's a good idea bro, I sure wouldn't want to be pricked in the middle of the night.
