Respect can be earnt (and lost) regardless of your age dependent on your actions and the sad thing is that a majority (or VERY vocal minority) of people in your age group act like tits.
They don't see it that way of course, instead they'll see it as being edgy, cool or simply one of the lads (it may have been a decade ago but I remember trying to be all three and, looking back on it, failing).
Either way, just be who you want to be and as long you don't become another one of the tits you'll be fine. Hell, I remember when playing the first MW the group I was with invited a 12 year old (shouldn't have been playing hey but hey ho) into our group as he was a funny, non-tittish guy.
