Here is a situation. need advice on if this is legal or harmful.
Say you have an 18 year old and a 15 year old and they fall in love through legit means and begin what they hope to be a permanent relationship. They have known each other for a while, are both mentally mature, and largely understand what they are getting into.
They both fully understand that the legal age of consent is 16, so they agree not to do anything sexual until this time. Say this is a long distance relationship, so there won't be a physical meeting at all and all online chats will avoid sexual discussion.
Is this legal?
Could this potentially harm the younger party by being in a relationship with someone older while they are still growing up? Are there hidden risks here? What are your opinions?
