Yup, you're the same guy all right.
Since two months after the fact no one in law enforcement has done anything, one of two things is the case:
1.) They tried, but were unable to identify you
2.) No one tried to identify you in the first place.
The odds of it being number one are very very low. The odds of it being number two are very, very high.
I will absolutely guarantee you with no exceptions whatsoever - no law enforcement agency would spend a full two months trying to identify someone who may have, but probably didn't, expose his genitals for a period of a nanosecond. If they were going to try to identify you and take any action, it would have been immediate. Since nothing has happened by now, either the answer to your question is NO, they were not able to easily identify you (or at all), or alternately they didn't try to identify you.
In either case, you asked if you are safe now? Yes. You are safe now. You can take that to the bank.
