How do you turn guys on?

Put your hand on the back of your boyfriend's head and start rubbing and stroking it gently, he'll love that. Yes, nibbling the ear does work, and I don't know about biting the neck but definitely kissing it gently does... it always sends shivers down my back when my girlfriend does that! You don't have to exactly touch his area, but just touch around it, like the top of his leg. Also when you kiss him, nibble his bottom lip, I can't think of a lad who doesn't enjoy this. As for fresh breath, you will need some gum handy, it never fails. If you haven't got any, just grab a drink such as coke; it's a last resort, but it works for some time!
