My husband is 5 years older than I am. However, to be on the safe side so neither of you get into trouble, check the state laws where you live. In my state, if you are under 18 years old and the other person is 3 or more years older, they can be charged with a crime such as statutory rape. If convicted, they would have to register as a sex offender for the rest of his/her life.
It's totally fine. what's not allowed is sex, he can get in jail if you guys do anything sexual because that's considered child pornography. I totally feel you, the guy I'm talking to is like 4 years older than me and I'm 17.
I second the advices given.
Being in a relationship with someone who is 5 years older is not wrong (assuming you both sincerely like one another). However if you are below 18, I would ask you put a hold on your sexual activities til you are above 18. Other than that, I see no wrong in dating someone who is 5 years older. :)
