I feel attracted to young girls, what to do?

Sir I am following your page for a long time, I like to get your opinion on this serious issue that I have I wanted to know what possible help there are for me. I have noticed that I have a growing sexual attraction to young girls (18 and younger). I am in my early twenties and have felt this way for some time. I want to get some therapy for this before this gets out of hand. What can I do and how get help?
Is there any way for me to do this without my family finding out? I still live with my immediate family and I am on their heath insurance

Thank you JP.

JP, I commend you for recognizing this and seeking help for it. As a parent and an Investigator I think your sense of responsibility here is something that more who feel the way you do should have. 

I recommend you find a psychiatrist as soon as possible. You recognize that it could get out of hand. Willpower can go a long way but a psychiatrist can help you with the options for treatment and keeping from violating the law and your own ethics. If you can't afford a psychiatrist, find a low-income clinic.
