Girls caught masturbating in boy's underwear.

It's something of a trope almost that quite a number of boys masturbate with/in girls/ladies underwear and often enough gt caught, giving rise to many an outraged or concerned parent/guardian.

However, I have never yet seen much about masturbating girls getting caught with boys underwear. I wonder how that is. have i been overlooking things or do girls just not experience any thrill to using boys/men's underwater for masturbatory purposes?
