swinging my dick around and making a joke are the opposite of mutually exclusive events.If that's how you know I really hope you aren't either. That being said, I'm sorry for making a joke while you were trying to swing your dick around and impress everybody.
My chemistry teacher dropped that knowledge on us my junior year in HS, when he was asked why it was called a "blowjob" if there was so much sucking involved. He didn't bat an eye and just said "because scientifically, there's no such thing as sucking. There's only blowing with negative pressure."
