Help I've lost interest in sexy stuff?

Im 14 male and I used to pop a ***** at girls jerk off everyday and night and be horny all the time now I don't get turned on when I see a sexy girl and I haven't jerked off for 3 days now I know I'm not turnin gay or anything cause I don't have any feelings towards males but I feel like I don't like girls or guys or anything is this me maturing or just low sex drive or testosterone????
