So isn't it a shame that they ignored his inability to give consent (due to age) and gave him a quick and somewhat disappointing coupling with a 'sex worker' as his only understanding of what love and sex are all about? Wouldn't you be disappointed if that was all you knew about it?
Putting the moral aspects aside for a moment, I don't think it would have been possible for him to have a meaningful experience given his age, maturity, and situation. By attempting to give him what they may have considered was the next best thing, they did him a disservice.
The adults should have known better.
