Well, my orientation when I was a little boy was heterosexual and my fantasies were focussed on adult or teenage women, I couldn't tell you how many nights I spent laying in bed longing for the embrace of a woman and to feel her breasts pressed against my back. I wanted female intimacy and if her hands had started to roam lower while we had been laying together, I would have welcomed it eagerly. Maybe even encouraged it myself. There was an incident where I got caught peeping on one of my female baby-sitters while she changed. I only tried it once and sadly, nothing ever came of it. I've mentioned before that memories like that influenced my acceptance of my own erotic attraction towards young girls. If little boys can desire intimate relationships with adult women to any degree as strongly as I did, than there must be little girls who have the same kind of desire for intimacy with a man.
I imagine I would have been freaked out if a man had made sexual advances towards me but I can admit that that might have depended on the person and if I already had a strong bond with them.
That being stated, I take issue with this statement:

"The point is that if you believe the stuff you spout about little girls being able to appreciate or be fulfilled by romantic relationships with older men (or women) who they're not sexually attracted to . . ."

I've never stated that, nor have I seen any other advocates of Girl-Love make a similar claim. I will give my attention and time to little girls but I will only make intimate advances towards them on a mutual basis: That basis being that she will have to show some indication that she desires intimate contact with me. I don't even mean sexual contact either, rather actions that indicate trust and affection; such as holding hands, hugs, cuddling, caressing someones face, etc. I take the same stance on sexual contact in that a potential partner would either have to do things such as telling me directly that they desire it, kiss me on the lips or masturbate in front of me. Even then, I would still ask if they want to do anything in specific terms.
Finally, I will note that I consider intimacy to be a precursor to sexual contact but also distinct from sexual contact. Arguably, it's just as important as sexual contact as it lets the person that you share it with know unequivocally that they are desired and approved of. Gaining this sense of intimacy from individuals besides ones parental units is an important step in affirming positive sexual identity and a sense of self-worth. Even in America, it used to be considered normal and acceptable for an adult friend to pick up a little girl and give her a hug or to put their arm around the shoulder of a young boy.
