It's not a good idea to use your email address as a your user name. You're setting yourself up for spam or worse.
You can always report it. First-degree sexual conduct has no limit on when prosecution begins. It would cover sexual penetration when you were under 13, possibly to 16 if he lived in the same household. The lesser sexual conduct charges, alas have a limitations period of ten years from occurance or when you turned 21 (which ever was later).
The real problem is if there is sufficient proof to convict. If all you have is your statement against his, you may be out of luck.
