All these replies about dealing with the sound -- I encourage a re-reading of the original post.
The poster mentioned that he wanted to *talk to his dad* about the pussy. Not that he was annoyed about hearing it!
My advice? You know your relationship with your dad better than any of us. I would have never even considered such a thing when I was younger, but now that I'm much older I joke around with my dad about stuff like that. So I'd probably feel comfortable asking if there was a girlfriend. (as it is, my parents are still together, and I don't want to know about *them together*, lol).
