She completely right when she says there’s little discussion with regards to penis in vagina sex and the pain and other issues that can occur, and what discussion there is nowhere near the level of anal sex. The disgust of some people in these discussions is completely invalid.
There should be no shame in receiving pleasure and since when is being pleased being oppressed? These close-minded people have no right to pass judgment on others, especially seeing as they are not effected by the private actions of others. What people do in the privacy of their own homes is the business of no one else as long as everyone is of age and consensual.
