Which sexual "immorality" is worse?

-Consentual sex between parent and off-spring (any age)? 
-Consentual sex between siblings? 
-Consentual sex between cousins?
-Consentual sex between pre-adult/teen and pre-adult/teen? 
-Consentual sex between pre-teen and pre-teen? 
-Consentual sex between pre-adult/teen and pre-teen?
-Consentual sex between an adult (other than parent/grandparent/etc.) and pre-adult/teen? (Assume the pre-adult/teen understands sex and does consent--legality is not the issue here)
-Consentual sex between an adult (other than parent/grandparent/etc.) and a pre-teen? (Assume the pre-teen understands sex and does consent--legality is not the issue here)
-Consentual sex between an adult and an adult who are un-wed?

Again, legal ramifications are not at issue, only your own personal "morality" towards these specific pairings.

A normal (healthy) relationship never starts sexual. If for example a 13-year old and a 25-year old get a relationship, and they both decide they want to have sex, what is really so wrong with that? Of course, we need to look into whether the "child" can make such a decision at such an age, but this is something that would need to be researched before it can be disputed or accepted. Right now, everyone is just mindlessly spouting the same mantra that "people cannot make rational decisions until they're 18".

You are perhaps talking about children that are not yet sexually aware. As you could have noticed if you had paid attention to my post, I explicitly stated I was not talking about those cases. As with the "rape" examples, it is yet another way of conservatives trying to turn away any sensible discussions of the topic of consensual sex between people with an age gap and to label all such people as child rapers/murderers.
