I am a 37m so I would say that I am not attracted to any ABDL Boys. Although I am curious to hear what makes ABDL Boys attractive because I am one. I love dressing like a baby/toddler/preschool boy (6mths to 5yrs) or a baby/toddler/preschool/little/big/preteen girl (6mths to 12yrs) that still love wearing diapers as much as possible. I always feel cute, pretty, adorable, but I am not sure what other people would think.
I have a Little brother who is chronologically younger than I. We don't know yet if his Little spirit is younger than mine or not, but we're excited to find out. I gotta say, the cutest thing about a Little boy, bABy or not, is Little spirits are very fragile, and there're times when they're hard to hide. Have a genuine major bowel or bladder blunder in front of someone you don't want being angry with you, and you'll see what I mean. In that moment where Littleness can't be hidden, and the tears are close, I can't imagine being able to hide how honored I'd feel that I'm the one a Little boy chose to let see his fragile spirit.
