Is my boyfriend normal down there?

I don't mean to like sound all groosss or like a perv but I wuz messing around with this guy n now i have sum questions. What are a guyz b@lls supposed to feel like? i don't know why they call them that because they are not really round......did soemthing happen to this guy where they got squished or something? How big r they supposed to any ways, like a golf ball or sumthing?
