Im pretty sure that any adult, age 18+, having any sort of relationship like that with a minor, is illegal. If you ever do have sex and someone found out, the adult could be charged with statutory rape, not good, means jail time. So as long as you are safe and everything's alright, just keep it quiet and it should be okay.
I DO NOT GO ON HERE ANYMORE. I HAVE LEFT THIS PLACE FOR GOOD AND DON'T INTEND ON COMING BACK. PLEASE DON'T FRIEND REQUEST ME, PRIVATE MESSAGE ME, OR ANYTHING BECAUSE I WILL NEVER SEE IT AND YOU'LL NEVER GET A RESPONSE. THANK YOU.
