Of course its a male. Raj told me a funny story about this guinea pig and him.
One day Raj, walks into the kids room and the pig is like "Hey baldy", Raj was confused as he thought to himself "is this this little fur ball talking to me??" The guinea pig then said, "I'll bet you $50 i can make you laugh out loud" Raj, who is always up for a bet said "why not, go for it" So the guinea pig whispered into his ear, I bet my dick is bigger then yours", suddenly Raj busted out laughing, paid his $50 and walked out of the room. The next day he walked into the room and the guinea pig said "hey you, the guy from 40 year old virgin, wanna bet again?" Raj then replied "you are on you little fucker, this time double or nothing. What are the odds?" The guinea pig said "I bet i can make you cry" Raj replied, "You are on"
The guinea pig then bent over lifted a leg and proved it!!
