I am a 20 year old male, I am dating a 17 year old female, In the state of Ohio is this illegal? Thanks

Dating, sure. No problem.

Stay out of her pants for another year minimum, or until after you get married, which ever comes first.

Wait a little bit like a year

The age of consent in Ohio is 16.

Most know me as a bull dog on dating of young people with older, but at 17 to 20, if all the parents are up on this, and have no issue, I don't see one myself
