Can I get removed from the Offender Registry?

I am a 20 year old male from Michigan and when I was 17 I was convicted of 2nd degree CSC for having consensual oral relations with a 12 year old (she was actually my 13 and it was ... the conviction was after a plea agreement). She was my girlfriend and I found out that she had previously been d many, many times by her father, as was her step sister. By the time I had met her she had consensually slept with at least 4 other guys around my age. She also continues to sleep with older men, as old as 21 and is now 16. The only reason i tell you all that part is because I have been criticized for taking her innocence in the past and victimizing her, and this is simply not true. Anyways. During the court dates and such, I had been evaluated by a criminal psychologist and it was determined that I was of no threat to society and had little to no chance of re-offending. I was sentenced to 8 months in jail, lifetime registry, and 2.5 years probation, serving 4 months in jail and finishing probation, which included a long treatment/rehabilitation program. I just finished my probation on January 28th and I was wondering, can I be removed from the offender registry? If so, when can I attempt to do so? Am I limited to how long I can wait before I do? How do I go about it? Can I talk to a lawyer about my case without paying hundreds or even thousands of dollars? These are all huge questions that I need answered, finding a job or place to live in Michigan is hard enough for people who aren't offenders, and being one, especially considering that what I did wasn't really all that bad morally, has really made my life difficult. I regret what I did and if I had a chance to go back it would never happen, but I don't have a time machine, so is there anything I can do, realistically?
