All men over 18, beware if you "date" or "talk" to any female under the age of 17.
A child under the age of 17, cannot consent to sex.
Even if they parents given you written permission, it's not enough.
If you are more than 2 years older then the girl then the "Romeo defense" flies out the window.
If in doubt, consult with a criminal attorney.
If you are convicted of sex with a minor then you end up a registered sex offender.
Your future employability will be greatly impacted.
Even if she says she is 17, 18, or 19 -- verify -- don't trust her. Even if she says she's old enough that is not good enough if you are arrested.
