Growing out of constant sexual thought?

Patient: I am gay and 17. I am literally attracted to almost any good looking, older male, and may even have fantasies about those men. Is this something I will grow out of? I do not want to be a pervert or thought of as one, especially since thats the last thing most people would think of me. Please help?

Symptoms: Fantasies, erections and masturbations.
