Hooking up all in itself is ok if that’s what both people want. Mutually agreed upon casual encounters could be ok. But honestly I think most decent men wouldn’t be suggesting hook ups to women. They’d not want men offering it to their sisters/daughters/nieces so they’d not do this to women. Maybe in their college years when very young and partying. Not as grown ups. Not in 30s/40s/50s/60s. That boat sailed.
