If your maturity is the same as a 16 year old, then I guess that's a plus. And the age difference is not that much for prosecutors to go after you. If you were 40, then prosecutors would be on you like flies on stink, regardless of the age of consent. Prosecutors like to make headlines too, it helps their careers.
The "norm" of society would probably say this is a sketchy relationship.
Personally I prefer more mature girls. I don't need the drama of physical or mental 16 year olds.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
