This includes pegging of course because I love a complete gender role reversal :)
For me, a true GDR is where the girl is the one who chase, lead, & more aggressive, while the guy is the one who's being chased, led, & more passive, and it's actually really hard to find any true GDR like this because the girl could be a bit more bold & forward, but at the end the guy is the one who chase & lead, and turn the tables on the girl. It's annoying to see it.
