Tansy/Abby I grew up in a facility and I've done plenty. Okay, so we can't rely on him to take the lead.
Try to tip your head the opposite way he has, fit either of your lips between both of his. Different people like different things - short kisses or longer ones. Try to figure out what he likes, and what you like, and come to a balance. You can use your hands - on his shoulders, in his hair, on his arms. And you can always just ask. If you bang your noses together or someone's teeth get in the way just laugh, it's not the end of the world. If he likes you, he'll just be happy to be kissing you, he doesn't need it to be perfect.
