Are you a prostitute if you have ?

im 13 and i live with my dad and my stepmom but she is almost my age cuz she is 19. shes mean to me and i dont like her and i dont like bein at home so i hang out wit my friends and they all have . they have with older men they meet on myspace and facebook and they told me i should do it so i made a myspace profile and lied about my age and said i was 18, i dont look 13 cuz im curvy and im latina and latina girls usually look older. neway i started meeting older men too and they would pick me up in the alley by my house and they take me to hotels and stuff, i had with maybe 20 guys but over a long time, like some months not at once and they were unprotected. my stepmom saw me get in a car in a alley and the next day she said i was a and she was going to tell my dad and i would go to jail. im not a and if i am i wasn't aware. can i get in trouble?
