There was a Friends episode that was just like this.
Rachel asked Ross if he talked to his friends about sex and he said, like STO did above, in very general or vague terms.
She asked him why and he said that guys don't want to tell other guys what they do with their S/O. That is true. If it were a one night stand, perhaps, but I'm not going to tell my best friend how tasty my wife's pussy is.
