No. There is no country where the legal age is greater than 18. However, sexual intercourse is something else, and each country has its laws; some Muslim nations require that a couple be married for sex to be legal.
No.
There are no laws about dating. There are laws about sexual contact. The age of consent in Florida is 17. so if he raped her yes he have to go to jail.
He should, but I believe 17 is a consensual age in Georgia.
Not in the United States. When the 17 year old becomes 18 and if they are sexually involved. Then it is illegal.
Of course not, it's only 2 years older.
You very definitely could.
Yes and the 19 year old can go to jail for that.
For dating? No.
A 23 year old should not be dating a 17 year old. Single Dating is when the dating person is ready to marry. The 17 year old is not ready at all. They should group date if they're going to date at all.
No, there are no laws about dating. There are laws about sexual contact, and in most places, including Texas, the age of consent is 16, though higher in a few places.
The 17 year old is a minor and the 26 year old an adult and if only dating is involved there is no problem. More than dating and the 26 year old could be arrested for rape.
Absolutely too young. Get away from that 17 year old, NOW!!
