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

If she aware that by give him a handjob would make him he 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 somehow pee in public and feel ashamed. Then he's too young.
