Considerations
Although I obviously prefer early pubescent bodies and prepubescent bodies, I can't say I'm completely indifferent to adult [female] bodies, especially when I get these violent moments of extremely high sex drive. But it rarely happens that I normally fantasize about
adult girls, as I don't care about them much.
A distinction between the living and the dead must be done though. I am very reluctant to get in a relationship with a living girl, and the idea of "normal" sex with an adult makes me feel empty inside. Big no no. So, paraphilic sex with an adult girl is ok, would be awesome, but normal sex is not and makes me sick. But normal sex would be ok for me (if legal) with early teens. Makes sense, doesn't it?
I give up. I can't find a reason for this. I don't know what makes this combination possible.
That was for living girls.
About dead girls...well....definitely long-term romantic relationship here would be totally natural to me. When I picture myself being in love with a dead girl all kinds of extremely romantic thoughts come to my mind, just like a non-paraphilic man would love his girlfriend/wife. I don't know how to explain, but for me, that would be the most natural romantic relationship, also the deepest one, one entire day wouldn't be enough to describe this. It would make me the happiest person on earth.
I would rather visit the grave of a dead girl and stay there forever (without doing anything illegal though) than date a living girl and go out with her.
Talking about necrophilia....children/early teens or adult girls? I'd say both, but with a strong, and I mean strong, to the point of being exclusive preference for adult girls - while it's basically the opposite thing for living girls. Makes perfect sense.

My pedophilia is mostly sexual, cause I find it hard to be connected with a child on an emotional level, I mean in a romantic way. Very hard. Maybe with girls ranging from 12 to 15 it would be more possible, but still, it'd be kinda weird because they don't have the level of maturity of adults.
The fact I might have feelings for a living girl though doesn't imply that I'd like a relationship with her. I don't like those long-committed romantic relationships at all, or all that dating stuff.
All of this is extremely weird, but also shows how the human mind, especially when it comes to sexuality and feelings of love is capable of being extremely multifaceted. My sexuality is certainly one of the most complex things I have ever analyzed.
So, at this point....to what extent am I an exclusive pedophile? It feels like living adult girls would just be some kind of exception, as it's not what I really like, while living children is what I normally look at when I'm outside or something.
IIs it possible to be something like 80%, 90% exclusive in a paraphilia? Like not 100%, but still exclusive.
