Is it normal that iv been really horny since i was 5 now 18, i love sex!!

Dont get me wrong i do believe in love, but i just love sex and those cute girls at the gym make me wanna bend them over and sock it to em' iv just been horny since i can remember, normally its a phase but idk about me, iv even considered being in porn sounds like it would be a great job, but sadly i dont live in Cali.
