See, i have this thing. When i'm not in the mood for any of the porn i have on my pc, i tend to jack off over girls i know from my school. These include this girl in my class, and some girls in other classes. I sometimes visualize myself having sex with them, which afterwards makes me feel like a creep because i'm only 14, and so are they. I'm scared it might be related to some kind of deep-seeded psychological issues.
Is there something wrong with me?
