I'm not sure how paying other women for sex if you're in a relationship fits in with a claim to be chivalrous.
What on earth has that got to do with it...
Chivalry is for me about how you treat the lady you are with or others around you while you are in their company
Just because someone is paying for sex outside of a relationship does not mean they don't love their partner or that they need to stop being a kind and courteous human being in their everyday life.
I for one very much appreciate the little things in life like a door held open, a chair pulled out in a restaurant, a hand on the small of my back to guide me or a you first gesture, there is so much beauty in those small things.
I love being an independent woman, I am fiercely defensive of my ability to do things for myself and I'm very capable, however it doesn't mean I cannot appreciate those small gestures or that I need to feel threatened by them.
Imo feminism has in some ways gone too far, women are almost afraid to accept a small act of chivalry with grace, because they feel its a sign of weakness and in some way challenges their independence or makes them less woman.
Feminism for me is not just about our strength and independence it is about grace in many forms.
Immasculation of men is not what feminism is about imo and the rejection of chivalry is one symptom of that.
