Why am i always sooo horny???

I masturbate at least once a day. With or without porn idc. And whenever i speak to my boyfriend over the phone i’m just finding him and his voice ssooooo sexxyyy and just whenever he talks. I’m getting turned on so easily and I cum at least twice a day! (18yrs old btw) but idk if the age even matters. Please guys idk why this is happening
