This is so unfair....?

ugh okay so im 15 and im a freshman in high school. but ive had my period since i was 10. and i am the oldest one in my cl. so lets just say i have ual feelings sometimes. like i get kinda horny sometimes...a little mor than most people. but im still considered too young to do anything. or doing anything would just be considered slutty. because the people who do things at my age just want attention. but honestly...i dont want attention. i just have these little feelings because i went through puberty really early. and its not like i can do stuff with a guy and make sure they dont tell. because they will tell. this is so unfair what do i do!? (oh and i dont beleive in like no before marriage so dont give me that)
