Actually, the definition of a pedophile is simply someone who is attracted sexually to children, whether they are happy about it or not and whether they consider it normal or not. Here's the official diagnostic definition:
http://www.behavenet.com/capsules/disor ... iliaTR.htm. For the record, there are three distinct categories which are generally lumped together under the term pedophile when the general public talks about it. However, the three terms are quite distinct and in fact are very distinct from a diagnosis and treatment perspective (from what I understand, pedophilia is impossible to change while hebephilia and ephebophilia can be turned to adult attractions, though I have not yet tried working with a therapist on it myself).
Pedophile refers specifically to someone who is sexually attracted to children (boys or girls or both, whether they are the same sex or the opposite sex) who have not undergone puberty yet.
Hebephile refers to someone who is sexually attracted to children currently going through puberty.
Ephebophile refers to someone who is sexually attracted to children who have just finished puberty but are still under the age of consent.
This last one is frankly really stupid if you ask me. Western culture worships youth and while we all know it's illegal for an adult to have sex with a 14-15 year old kid, the fact remains that most adults with homo or hetero sexual desires, if they're honest (many are not because of the witch hunt atmosphere we have in the world regarding anything to do with pedophilia or anything that sounds like it) will admit to finding teenagers attractive. Seinfeld even did a whole show about it with George staring too long at a 15 year old girl's breasts. While officially it's supposed to be considered "sick" and frowned upon to find such kids attractive, the reality is that most adults do find them attractive but simply know enough not to act on it.
Anyway, getting back to your own questions, for me I find I'm attracted to the entire gamut of boys, from around age 8 all the way into early adulthood (i.e. early 20s) though my fantasies usually tend to revolve around kids around 10-14 years of age which would peg me as a hebephile as opposed to a pedophile. I personally don't like the feelings I have about being attracted sexually to children and would change it if I could.
I also find that in most cases, it's a matter of lust for me rather than love. However, I think in that respect, I'm like most other "normal" people (normal in the sense of people who aren't attracted to children not in the sense of saying that I'm not normal for whatever I am).
For most people, the initial interest they feel in someone they might eventually have sex with or want to eventually have sex with is a feeling of lust -- of feeling someone is pretty or "hot" as you put it (for some reason, I tend to look at boys and think to myself, he's so pretty or he's so gorgeous as opposed to thinking he's so hot, but not sure what to make of that). The feeling of love comes once a relationship has deepened -- something which happened to me only once when I did fall in love with a 13 year old boy (though I never did anything about it from a sexual standpoint other than having a fantasy about him -- I never told him how I felt about him and never touched him in a sexually suggestive way).
Hope that helps.
Bottom line, whatever it is you are feeling, you need to accept that you feel it and then try to move on so that you can live your life. It's not perfect, but so far that's the best I've been able to come up with. Others seem to feel that aversion therapy where you either associate this with something disgusting or where you force yourself to see your desires as pure evil works, but for me I've found that trying that just makes my desires get stronger.
