How horny do teenage boys get ?? this normal ?

so when i went to the movies with my boyfriend the other day, he was all over me. which is nice, deffinently no objections, i was just wondering if it's normal. he snuggled up next to me, and was stroking my arm and hand, he kept kissing my neck and cheek telling me i was so hot and i smelt so good, then his hand leaned over and felt up my chest, then later on in the movie he tried to touch my 'down there' through my dress and undies, i kinda gave him the message not to do that and he was fine about it, but is he like really horny or something? we've made out heaps and felt each other up, does he want more ?
