Yes, and that's why in sexually repressed time periods like the 1950s, women were significantly less oppressed. Wait...
Its tough, because we can make arguments that porn is bad, but we also know for a fact that purity culture is one of the cornerstones of the patriachy.
Do we really want to ramp purity culture back up on the off chance it makes people like BDSM or something slightly less?
It degrades and oppresses all women.
