Since I think genuine childhood sexual interest in adults is very rare, those possibilities weigh heavily in comparison.

No matter how many testimonies, how much anecdotal evidence there is, how many people talk about their own childhood experiences and fantasies...you're still clinging to this???

You are kidding yourself if you don't think that there are plentyyyyy of pubescent kids who fantasize about and would love a sexual experience with an attractive adult of their preferred gender.
