Ice cube masturbating NEED ADVICE

Okay so I have masturbated many times but is it weird I only ever can cum and achieve an orgasm when I am masturbating over photos of ice cube, I mean I think he's daddy AF. He's so sexy and he's the only man who can get me off. I am 14 and I have asked my boyfriend if he can try rap his verse from " I ain't the one" during oral encounters, but he gets offended and a little uncomfortable. Is something wrong with me??? I literally can only orgasm I can see ice cube.
