Help--Sexually deviant thoughts.?

I try to be a good person and have never tried to do anything to hurt people. but I'm messed up in the head, and I don't know if there is a fix. I'm a female in her mid-twenties and this all started being consistent for a little over a year (about a month after my boyfriend moved away) ago. At first, I thought it was a fluke thing, but it just got worse. I have never hurt anyone like this and never will, but I am worried and paranoid about my problem. I am sexually attracted to a few men my age, but a lot of times my thoughts go to people I shouldn't be attracted to--you name any person I'm not supposed to be attracted to, and I am. People can sometimes tell, and it causes problems for me at work and school and in the community. I am seeing a psychiatrist, but I'm really embarrassed about it and don't know if anything can be done. Also, I am studying and have plans on what I want to do with my life. This is just a major hindrance. I feel like I can't tell anyone who knows me, not my family, not my ex-boyfriend who is still in love with me and who I wish I could start a life with. I was wondering if there were any treatments (meds, therapy, etc.) for this. I don't know what to do. This all needs to be kept confidential so it won't affect my anxiety and paranoia and how people treat me because I already get treated like crap by a lot of people (even ones who don't know about this like my parents). I don't want anything to go in my file that might affect my chances at practicing medicine (what I'm starting to study). I haven't acted on anything and won't. I keep praying about it, but other than that, I haven't done anything. I want my normal life back. I wasn't this screwed up 2 years ago, and I don't know what happened to me. I want the bad sexual thoughts to go away. Please give me sincere advice only. Is there any kind of treatment? How much would it cost? If I paid cash for everything would it not have to be in my file? Could my doc just prescribe something and I pick it up at the pharmacy? If I have to have some kind of counseling, can they give me any kind of reason (like my other problems like depression) they want and not mention anything I don't want in my file about it? Would I have to pay out of pocket if I wanted my records safe? Can I look at my file? Is there any hope at all?
