Fan theory. Since mamono can detect men's desire, so they may able to predict the outcome of sex.

If she's aware that by give a boy a handjob would make him feel good and looking toward even more fun, then he's ready (even if he protest a lot at first).

But if it would leave him crying like baby upon cumming, think that he's forced to pee in public and feel ashamed. Then he's too young.
