For instance, I have myself yet just been pegged by two girls.
The first girl was a bit younger than me but very confident about herself. Earning a lot more money than I do and being used to commanding men, even in professional life. From the first second of our meeting it was clear that she will be in charge and pegging was just one side of this.
The other girl was even more dominant and she didn´t even undress. I felt that for her it was not about the sensuality of anal stimulation and more about the act of humiliation. I also wouldn´t do this kind of pegging again.
I think I know what you mean. I did mysef get into strapon sex just recently.
Have always been dominant but taking a guy with a strapon really is the perfect extension for this.
I actually believe that this may just be the manifestation of a shift in gender roles.
These days it is acceptable that women earn more than men, women can be dominant, guys can be shaved and it is nowadays accepted when a guy is in the sub role and gets penetrated by a girl.
My guess is that many women and men would always have liked to try strapon pegging but only now, when social conventions seem to be growingly lifted, such sexual endeavours are taken.
Personally I like both types of pegging. The one where I give very special pleasure to a guy and the one where I peg to humiliate a guy ,-)
