I have been speaking to this lad on fb and he seems really nice, he is my mates mate so he's not like a randomer and we've been geting on well but I'm just fed up of only speaking to him on facebook and I'd rather text and ring him but I wanna ask him for his mobile number but I don't want it to seem like I'm stalkerish and I am gunna pester him constantly so how do I ask him?
