You're right in this case, as the 18 year old is legally an adult, and therefore legally allowed to decide who he/she wants to date (as long as that person is also an adult).
But age does matter. If this person weren't an adult the answers on this thread would be very different. At fifteen you cannot decide who you want to date, that decision is your parents, and even they don't have complete control. For instance, most places have a legal age of consent of at least 16, which means if you date someone, and have sex, they will be charged with statutory rape. That's the law. Your parents cannot consent to sexual activity, nor can you.
