They did not come on their own, you probably were exposed to things yu shouldn't have seen, which may have ended in some kind of trauma, and it has probably messed up your "own" sexuality, the one you would have had naturally and spontaneously (happens to many adults who watch p 0 r n and the kind, they get so disconnected and end up wanting things or thinking about things they would have found weird if not "exposed" to it). Well then it is ok to have sexual desire, but what you seem to describe sounds like a "displacement", you may be craving something else like love or care. Maybe when you meet someone you feel good with you'll feel your desire is true desire and enjoyment of intimacy and it could make things better. In the mean time I guess you could just avoid everything that is sex like p 0 r n etc...
